Created xlsx file delete written formula

Question

I create an excel file via slsxwriter and want to put there a formula. I'm doing it like this:

sheet.write(2, 6, "=IF(AND(ISBLANK(J2); ISBLANK(K2); ISBLANK(L2)); \\"PASSED\\"; \\"FAILED\\")")

trying also this:

sheet.write_formula(2, 6, "=IF(AND(ISBLANK(J2); ISBLANK(K2); ISBLANK(L2)); \\"PASSED\\"; \\"FAILED\\")")

But when I later open created xlsx file, excel want to 'repair' my file and is deleting the formula... (Removed Records: Formula from /xl/worksheets/sheet1.xml part)

When I was putting it by hand in excel it works great.

Anyone has an idea what is going on?

Answer 1

Formulas are stored in Excel in US English, no matter what language you are actually using. The US English separator is the comma ( , ), not semicolon ( ; ).

See the section titled "Non US Excel functions and syntax" in the chapter "Working with Formulas" in the official documentation.
