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.
Microsoft Excel up until 2007 version used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format. Excel 2007 uses Office Open XML as its primary file format, an XML-based format that. Hello, Welcome to Microsoft Community and thank you for posting the question. From your description I understand that it takes longer time to open an Excel file. I will assist you to resolve this issue, however I. I have MS Office 2007, Windows 7. When I double click on an xls file Excel opens up but it is just a empty excel program. It is similar to opening up excel and then just closing the book1 that opens up automatically. Just a.

How can I read an Excel file directly into R? Or should I first export the data to a text- or CSV file and import that file into R? You can use a library called ExcelLibrary. It's a free, open source library posted on Google Code: ExcelLibrary. This looks to be a port of the PHP ExcelWriter that you mentioned above. It will not write to the new.xlsx. I'm using Debian Linux and I want to convert a CSV file to an Excel XLS Spreadsheet file. The catdoc package includes the xls2csv command that converts from XLS to CSV. However it doesn't do the re.

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,[4] using a grid of cells arranged in numbered rows and letter- named columns to organize data manipulations like arithmetic operations. 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).[5] 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,[6][7] 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,[8] or in general, as a design tool that asks the user questions and provides answers and reports.[9][1. In a more elaborate realization, an Excel application can automatically poll external databases and measuring instruments using an update schedule,[1. Word report or Power.
Point slide show, and e- mail these presentations on a regular basis to a list of participants. Use of a user- defined function sq(x) in Microsoft Excel. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel.
Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y. Graph made using Microsoft Excel. Microsoft allows for a number of optional command- line switches to control the manner in which Excel starts.[1. Macro programming. VBA programming. The Windows version of Excel supports programming through Microsoft's Visual Basic for Applications (VBA), which is a dialect of Visual Basic. 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[1. VBA was removed from Mac Excel 2.
VBA engine natively to Mac OS X. VBA was restored in the next version, Mac Excel 2. Active. X objects, impacting some high level developer tools.[1. A common and easy way to generate VBA code is by using the Macro Recorder.[1. 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 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,[1. 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. Beginning with version 5.
Excel recorded macros in VBA by default but with version 5. XLM recording was still allowed as an option. After version 5. 0 that option was discontinued.
All versions of Excel, including Excel 2. XLM macro, though Microsoft discourages their use.[2. Charts. Excel supports charts, graphs, or histograms 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. Data storage and communication. Number of rows and columns. Versions of Excel up to 7. K (2. 14 = 1. 63. Versions 8. 0 through 1. K (2. 16 = 6. 55.
IV'). Version 1. 2. M (2. 20 = 1. 04. XFD') columns.[2. File formats. Microsoft Excel up until 2. Excel Binary File Format (. XLS) as its primary format.[2.
Excel 2. 00. 7 uses Office Open XML as its primary file format, an XML- based format that followed after a previous XML- based format called "XML Spreadsheet" ("XMLSS"), first introduced in Excel 2. Although supporting and encouraging the use of new XML- based formats as replacements, Excel 2. In addition, most versions of Microsoft Excel can read CSV, DBF, SYLK, DIF, and other legacy formats. Support for some older file formats was removed in Excel 2. The file formats were mainly from DOS- based programs. Binary. Open. Office.
Excel format.[2. 6] Since then Microsoft made the Excel binary format specification available to freely download.[2. XML Spreadsheet. The XML Spreadsheet format introduced in Excel 2.
XML based format missing some more advanced features like storage of VBA macros. Though the intended file extension for this format is . XML files with . xls extension. This feature is widely used by third- party applications (e. My. SQL Query Browser) to offer "export to Excel" capabilities without implementing binary file format.
