Using nested formulas in xlsxwrtier

i am trying to generate an excel sheet with python and xlsxwriter and i want to have the following formula in the cell:

=IFERROR(AVERAGE(A1:A10);"")

whereas my german excel would show this as

=WENNFEHLER(MITTELWERT(A1:A10);"")

but i dont really think the language aspect is making a difference.

It works nicely as long as i am doing:

worksheet.write_formula(l+4,1+k,"=AVERAGE(%s%s:%s%s)"%(chr(65+1+k),4,chr(65+1+k),l+4))

what does not work is using nested formulas. Excel always errors upon opening the sheet. I think this should be working:

worksheet.write_formula(l+4,1+k,"=IFERROR(AVERAGE(%s%s:%s%s);0)"%(chr(65+1+k),4,chr(65+1+k),l+4))

I believe i am making either a syntax mistake or hitting a limitation in xlsxwriter. Does somebody know how this works in xlsxwriter.

I was unable to find nested formulas in the docs or any examples of this elsewhere. Is this even possible?

Best,

The formula should work but you'll need to change from semi-colons to commas. See the Working with Formulas section of the XlsxWriter docs where this, and some other differences between Excel formulas are explained:

Also, formulas must be written with the US style separator/range operator which is a comma (not semi-colon). Therefore a formula with multiple values should be written as follows:

    worksheet.write_formula('A1', '=SUM(1, 2, 3)')   # OK
    worksheet.write_formula('A2', '=SUM(1; 2; 3)')   # Semi-colon. Error on load.

There is also a link in that doc to this handy Formula Translator.

Finally you may want to also have a look at the Cell Utility Functions that XlsxWriter provides and which might help you create the range within the formula.
