The Excel-2010 tag is used for referencing the Excel Version 2010 spreadsheet application from Microsoft. If your question is about VBA then also tag it VBA. If it is about an Excel formula or worksheet function, then tag it worksheet-function.
Excel 2010 is the 14th version of Microsoft's commercial spreadsheet program. Microsoft made slight user interface (UI) changes; otherwise, it continues to use the UI pioneered in Office 2007.
Features such as Sparklines and Slicers were introduced in Excel 2010 to provide more charting and data visualization power.
This tag is used for questions specific to the 2010 version of the program. However, it is usually used in tandem with other tags, to let SO users know what your question is about. If your question is about VBA then also tag it vba. If it is about an Excel formula, tag it excel-formula or worksheet-function. Questions about addins for Excel 2010 should be tagged excel-addins.
