Microsoft Excel File Compatibility
Spreadsheet
File formats tested with Microsoft Excel
Compare tested file formats for Microsoft Excel. Each compatibility report separates the ability to open a file from how editable it remains after import.
Understanding file support in Microsoft Excel
File support is more than whether Microsoft Excel recognizes an extension. Imported content may remain fully editable, become partially converted or lose parts of its original structure.
A Yes result means the format works in the application's normal documented workflow.
Some formats require specific conditions or lose meaningful structure during import.
Scores summarize practical compatibility but should be read together with the detailed report.
