Getting error with Excel formulas

The formula itself looks valid, so if it works in Excel for the web but produces a syntax error in the desktop application, the issue is most likely related to your desktop Excel's regional settings rather than the formula itself.

Many desktop installations of Excel use semicolons (;) instead of commas (,) to separate function arguments. Try replacing the commas with semicolons so the formula becomes =DATEDIF(E2;TODAY();"Y")-5. If this works, your Excel is configured to use semicolons as the list separator.

Another possibility is that the value in cell E2 is stored as text instead of a real date. Although your screenshot suggests a parsing error rather than a data issue, it is still worth confirming that E2 contains a valid Excel date.

You can also test whether your Excel uses commas or semicolons by entering either =SUM(1,2) or =SUM(1;2). Whichever formula works indicates the correct argument separator for your installation.
