Converting and Opening Unsupported File Formats

While there are file converters out there, the most common way to get an unsupported file format into Excel is:

  1. Open the unsupported data file with the software used to create it.

  2. Use the Save As or Export functions to save the file in either Comma-Separated Values (CSV) or XLS(If Supported) file format.

  3. Once that is done you can Open it into Excel 2010.

Note: XLS will retain formulas, CSV will not.
