In addition, it can display data as line graphs, histograms and charts, and with a very limited three-dimensional graphical display. It allows sectioning of data to view its dependencies on various factors for different perspectives (using and the scenario manager). It has a programming aspect, Visual Basic for Applications, allowing the user to employ a wide variety of numerical methods, for example, for solving differential equations of mathematical physics, and then reporting the results back to the spreadsheet.

It also has a variety of interactive features allowing user interfaces that can completely hide the spreadsheet from the user, so the spreadsheet presents itself as a so-called application, or decision support system (DSS), via a custom-designed user interface, for example, a stock analyzer, or in general, as a design tool that asks the user questions and provides answers and reports. In a more elaborate realization, an Excel application can automatically poll external databases and measuring instruments using an update schedule, analyze the results, make a report or slide show, and e-mail these presentations on a regular basis to a list of participants. Excel was not designed to be used as a database. Microsoft allows for a number of optional command-line switches to control the manner in which Excel starts. FunctionsExcel 2016 has 484 functions. Of these, 360 existed prior to Excel 2010. Microsoft classifies these functions in 14 categories.

Of the 484 current functions, 386 may be called from as methods of the object 'WorksheetFunction' and 44 have the same names as VBA functions. Macro programming VBA programming. Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y.The Windows version of Excel supports programming through Microsoft's (VBA), which is a dialect of. Programming with VBA allows spreadsheet manipulation that is awkward or impossible with standard spreadsheet techniques. Programmers may write code directly using the Visual Basic Editor (VBE), which includes a window for writing code, debugging code, and code module organization environment. The user can implement numerical methods as well as automating tasks such as formatting or data organization in VBA and guide the calculation using any desired intermediate results reported back to the spreadsheet.VBA was removed from Mac Excel 2008, as the developers did not believe that a timely release would allow porting the VBA engine natively to Mac OS X. VBA was restored in the next version, Mac Excel 2011, although the build lacks support for objects, impacting some high level developer tools.A common and easy way to generate VBA code is by using the Recorder.

The Macro Recorder records actions of the user and generates VBA code in the form of a macro. These actions can then be repeated automatically by running the macro. The macros can also be linked to different trigger types like keyboard shortcuts, a command button or a graphic. The actions in the macro can be executed from these trigger types or from the generic toolbar options. The VBA code of the macro can also be edited in the VBE. Certain features such as loop functions and screen prompt by their own properties, and some graphical display items, cannot be recorded but must be entered into the VBA module directly by the programmer. Advanced users can employ user prompts to create an interactive program, or react to events such as sheets being loaded or changed.Macro Recorded code may not be compatible with Excel versions.

Some code that is used in Excel 2010 cannot be used in Excel 2003. Making a Macro that changes the cell colours and making changes to other aspects of cells may not be backward compatible.VBA code interacts with the spreadsheet through the Excel Object Model, a vocabulary identifying spreadsheet objects, and a set of supplied functions or methods that enable reading and writing to the spreadsheet and interaction with its users (for example, through custom toolbars or command bars and message boxes). User-created VBA execute these actions and operate like macros generated using the macro recorder, but are more flexible and efficient.HistoryFrom its first version Excel supported end user programming of macros (automation of repetitive tasks) and user defined functions (extension of Excel's built-in function library). In early versions of Excel these programs were written in a macro language whose statements had formula syntax and resided in the cells of special purpose macro sheets (stored with file extension.XLM in Windows.) XLM was the default macro language for Excel through Excel 4.0. Beginning with version 5.0 Excel recorded macros in VBA by default but with version 5.0 XLM recording was still allowed as an option. After version 5.0 that option was discontinued. All versions of Excel, including Excel 2010 are capable of running an XLM macro, though Microsoft discourages their use.

Made using Microsoft ExcelExcel supports, or generated from specified groups of cells. The generated graphic component can either be embedded within the current sheet, or added as a separate object.These displays are dynamically updated if the content of cells change. For example, suppose that the important design requirements are displayed visually; then, in response to a user's change in trial values for parameters, the curves describing the design change shape, and their points of intersection shift, assisting the selection of the best design.Add-insAdditional features are available using. Several are provided with Excel, including:.

Solver Add-In: Tools for optimization and equation solvingData storage and communication Number of rows and columnsVersions of Excel up to 7.0 had a limitation in the size of their data sets of 16K (2 14 = 16 384) rows. Versions 8.0 through 11.0 could handle 64K (2 16 = 65 536) rows and 256 columns (2 8 as label 'IV').

Version 12.0 onwards, including the current Version 16.x, can handle over 1M (2 20 = 1 048 576) rows, and 16 384 (2 14 as label 'XFD') columns. File formats Excel Spreadsheet.xls, (.xlsx,.xlsm,.xlsb - Excel 2007)application/vnd.ms-excelcom.microsoft.excel.xlsDeveloped byType of formatMicrosoft Excel up until 2007 version used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format. Excel 2007 uses as its primary file format, an XML-based format that followed after a previous -based format called 'XML Spreadsheet' ('XMLSS'), first introduced in Excel 2002.Although supporting and encouraging the use of new XML-based formats as replacements, Excel 2007 remained backwards-compatible with the traditional, binary formats.

In addition, most versions of Microsoft Excel can read, and other legacy formats. Support for some older file formats was removed in Excel 2007. The file formats were mainly from DOS-based programs.Binaryhas created documentation of the Excel format. Since then Microsoft made the Excel binary format specification available to freely download.

XML Spreadsheet. Main article:The XML Spreadsheet format introduced in Excel 2002 is a simple, based format missing some more advanced features like storage of VBA macros. Though the intended file extension for this format is.xml, the program also correctly handles XML files with.xls extension. This feature is widely used by third-party applications (e.g. Query Browser) to offer 'export to Excel' capabilities without implementing binary file format. The following example will be correctly opened by Excel if saved either as Book1.xml or Book1.xls.

DDE: 'Dynamic Data Exchange' uses the message passing mechanism in Windows to allow data to flow between Excel and other applications. Although it is easy for users to create such links, programming such links reliably is so difficult that Microsoft, the creators of the system, officially refer to it as 'the protocol from hell'. In spite of its many issues DDE remains the most common way for data to reach traders in financial markets. Network DDE Extended the protocol to allow spreadsheets on different computers to exchange data. Starting with Windows Vista, Microsoft no longer supports the facility. Real Time Data: RTD although in many ways technically superior to DDE, has been slow to gain acceptance, since it requires non-trivial programming skills, and when first released was neither adequately documented nor supported by the major data vendors.Alternatively, provides browsing within Microsoft Excel.

Main article:Microsoft Excel protection offers several types of passwords:. Password to open a document.

Password to modify a document. Password to unprotect worksheet.

Password to protect workbook. Password to protect the sharing workbookAll passwords except password to open a document can be removed instantly regardless of Microsoft Excel version used to create the document. These types of passwords are used primarily for shared work on a document. Such password-protected documents are not, and a from a set password is saved in a document's. Password to protect workbook is an exception – when it is set, a document is encrypted with the standard password “ VelvetSweatshop”, but since it is known to public, it actually does not add any extra protection to the document.

Gameshark cheat codes for pokemon sapphire vba.

The only type of password that can prevent a trespasser from gaining access to a document is password to open a document. The cryptographic strength of this kind of protection depends strongly on the Microsoft Excel version that was used to create the document.In Microsoft Excel 95 and earlier versions, password to open is converted to a 16-bit that can be instantly cracked. In Excel 97/2000 the password is converted to a 40-bit key, which can also be cracked very quickly using modern equipment. As regards services which use (e.g. Password-Find), it takes up to several seconds to remove protection.

In addition, password-cracking programs can passwords at a rate of hundreds of thousands of passwords a second, which not only lets them decrypt a document, but also find the original password.In Excel 2003/XP the encryption is slightly better – a user can choose any encryption algorithm that is available in the system (see ). Due to the CSP, an Excel file can't be decrypted, and thus the password to open can't be removed, though the brute-force attack speed remains quite high. Nevertheless, the older Excel 97/2000 algorithm is set by the default. Therefore, users who do not change the default settings lack reliable protection of their documents.The situation changed fundamentally in Excel 2007, where the modern algorithm with a key of 128 bits started being used for decryption, and a 50,000-fold use of the hash function reduced the speed of brute-force attacks down to hundreds of passwords per second. In Excel 2010, the strength of the protection by the default was increased two times due to the use of a 100,000-fold SHA1 to convert a password to a key.Microsoft Excel ViewerMicrosoft Excel Viewer was a freeware program for viewing and printing spreadsheet documents created by Excel.

The Microsoft Excel Viewer was retired in April, 2018 in lieu of Excel Online. Excel Viewer is similar to in functionality. (There is not a current version for the.) Excel Viewer is available for and, such as the. It is also possible to open Excel files using certain online tools and services. Online excel viewers do not require users to have Microsoft Excel installed.

QuirksIn addition to in general, other problems specific to Excel include numeric precision, misleading statistics functions, mod function errors, date limitations and more.Numeric precision. Excel maintains 15 figures in its numbers, but they are not always accurate: the bottom line should be the same as the top line.Despite the use of 15-figure precision, Excel can display many more figures (up to thirty) upon user request. But the displayed figures are not those actually used in its computations, and so, for example, the difference of two numbers may differ from the difference of their displayed values. Although such departures are usually beyond the 15th decimal, exceptions do occur, especially for very large or very small numbers. Serious errors can occur if decisions are made based upon automated comparisons of numbers (for example, using the Excel If function), as equality of two numbers can be unpredictable.

In the figure the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using Excel.

Because the sum in the second line has only eleven 1's after the decimal, the difference when 1 is subtracted from this displayed value is three 0's followed by a string of eleven 1's. However, the difference reported by Excel in the third line is three 0's followed by a string of thirteen 1's and two extra erroneous digits. This is because Excel calculates with about half a digit more than it displays.Excel works with a modified 1985 version of the.

Excel's implementation involves conversions between binary and decimal representations, leading to accuracy that is on average better than one would expect from simple fifteen digit precision, but that can be worse. See the main article for details.Besides accuracy in user computations, the question of accuracy in Excel-provided functions may be raised. Particularly in the arena of statistical functions, Excel has been criticized for sacrificing accuracy for speed of calculation.As many calculations in Excel are executed using, an additional issue is the accuracy of VBA, which varies with variable type and user-requested precision. Statistical functionsThe accuracy and convenience of statistical tools in Excel has been criticized, as mishandling missing data, as returning incorrect values due to inept handling of round-off and large numbers, as only selectively updating calculations on a spreadsheet when some cell values are changed, and as having a limited set of statistical tools.

Microsoft has announced some of these issues are addressed in Excel 2010. Excel MOD function errorExcel has issues with. In the case of excessively large results, Excel will return the error warning #NUM! Instead of an answer. Fictional leap day in the year 1900Excel includes February 29, 1900, incorrectly treating 1900 as a, even though e.g. 2100 is correctly treated as a non-leap year. The bug originated from (deliberately implemented to save computer memory), and was also purposely implemented in Excel, for the purpose of.

This release was a major upgrade from the previous version. Similar to other updated Office products, Excel in 2007 used the new menu system. This was different from what users were used to, and was met with mixed reactions. One study reported fairly good acceptance by users except highly experienced users and users of word processing applications with a classical, but was less convinced in terms of efficiency and organisation. However, an online survey reported that a majority of respondents had a negative opinion of the change, with advanced users being 'somewhat more negative' than intermediate users, and users reporting a reduction in productivity.Added functionality included the set of editable business diagrams.

Also added was an improved management of named variables through the Name Manager, and much improved flexibility in formatting graphs, which allow ( x, y) coordinate labeling and lines of arbitrary weight. Several improvements to pivot tables were introduced.Also like other office products, the file formats were introduced, including.xlsm for a workbook with macros and.xlsx for a workbook without macros.Specifically, many of the size limitations of previous versions were greatly increased. To illustrate, the number of rows was now 1,048,576 (2 20) and columns was 16,384 (2 14; the far-right column is XFD). This changes what is a valid A1 reference versus a named range. This version made more extensive use of multiple cores for the calculation of spreadsheets; however, VBA macros are not handled in parallel and XLL add‑ins were only executed in parallel if they were and this was indicated at registration.Excel 2010 (v14.0).
