Microsoft Excel - Wikipedia, the free encyclopedia. Microsoft Excel is a spreadsheet developed by Microsoft for Windows, Mac OS X, Android and i. OS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1. Lotus 1- 2- 3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office. Features. Basic operation. Microsoft Excel has the basic features of all spreadsheets. It has a battery of supplied functions to answer statistical, engineering and financial needs. 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 pivot tables and the scenario manager). 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. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel. 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. Excel 2013 is the spreadsheet application in the Microsoft Office 2013 suite.

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 prompts 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 between Excel versions. Some code that is used in Excel 2. Excel 2. 00. 3. Making a Macro that changes the cell colors and making changes to other aspects of cells may not be backward compatible. VBA code interacts with the spreadsheet through the Excel Object Model. User- created VBA subroutines execute these actions and operate like macros generated using the macro recorder, but are more flexible and efficient. History. From 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. After version 5. 0 that option was discontinued. All versions of Excel, including Excel 2. XLM macro, though Microsoft discourages their use. 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.

Password to protect workbook is an exception . 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 9. In Excel 9. 7/2. 00. As regards services which use rainbow tables (e. Password- Find), it takes up to several seconds to remove protection. In addition, password- cracking programs can brute- force attack 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 2. 00. 3/XP the encryption is slightly better . 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 9. In Excel 2. 01. 0, the strength of the protection by the default was increased two times due to the use of a 1. SHA1 to convert a password to a key. Microsoft Excel Viewer.
