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. Therefore, users who do not change the default settings lack reliable protection of their documents. Due to the CSP, an Excel file cannot be decrypted, and thus the password to open cannot be removed, though the brute-force attack speed remains quite high.

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.citation needed 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. Microsoft Excel Viewer was a freeware program for Microsoft Windows for viewing and printing spreadsheet documents created by Excel. Excel for the web can display most of the features available in the desktop versions of Excel, although it may not be able to insert or edit them.

Microsoft Excel 2007, along with the other products in the Microsoft Office 2007 suite, introduced new file formats. Though the intended file extension for this format is .xml, the program also correctly handles XML files with .xls extension. In addition, most versions of Microsoft Excel can read CSV, DBF, SYLK, DIF, and other legacy formats. Excel 2007 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 888starz 2002.

Use the fill handle in Excel to quickly copy a formula to other cells. Learn how to hide a column, unhide all columns, hide cells, and much more. Use CONCATENATE, TEXTJOIN or Flash Fill to merge cells without losing data. A loop in Excel VBA enables you to loop through a range of cells with just a few codes lines. Excel introduced auto-fill, the ability to drag and expand the selection box to automatically copy a cell or row contents to adjacent cells or rows, adjusting the copies intelligently by automatically incrementing cell references or contents. It also introduced intelligent cell re-computation, where only cells dependent on the cell being modified are updated (previous spreadsheet programs recomputed everything all the time or waited for a specific user command).

If text is entered that happens to be in a form that Excel interprets as a date, the text can be unintentionally changed to a standard date format. Excel supports dates with years in the range 1900–9999, except that December 31, 1899, can be entered as 0 and is displayed as 0-jan-1900. Thus, a formula counting dates between (for example) February 1, 1900 and March 1, 1900 will return an incorrect result. 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. Excel works with a modified 1985 version of the IEEE 754 specification.

The cryptographic strength of this kind of protection depends strongly on the Microsoft Excel version that was used to create the document. All passwords except password to open a document can be removed instantly regardless of the Microsoft Excel version used to create the document.

Excel users can access external data sources via Microsoft Office features such as (for example) .odc connections built with the Office Data Connection file format. This feature is widely used by third-party applications (e.g. MySQL Query Browser) to offer “export to Excel” capabilities without implementing binary file format. Up until the 2007 version, Microsoft Excel used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format.
