What to expect

  • Any VBA macros in the original XLS are not carried into the plain-text DIF.

Frequently asked questions

What is preserved when converting XLS to DIF?
DIF stores only cell values in rows and columns, so the data grid carries over as plain values while formatting, fonts and cell styling do not.
Why convert an XLS spreadsheet to DIF?
DIF is a simple, long-established plain-text interchange format for moving a single sheet of tabular data between programs that may not read the binary XLS format.
What happens to formulas and multiple sheets?
DIF holds one sheet of values only, so formulas are reduced to their computed results and any additional worksheets in the workbook are not included.
Where can the DIF file be opened?
DIF loads as a normal grid in spreadsheet programs such as Microsoft Excel, LibreOffice Calc and Google Sheets.
