All users who wish to view and recalculate values using the embedded Python functionality in Excel will need to have PyXLL, Python, and Excel loaded on their machines.
We offer multi-user discounts to meet this need. Please contact us if you have any questions about pricing, or would require a large number of users to have PyXLL installed.
What happens if I send my spreadsheet to a user that does not have PyXLL or Python installed?
The results of the Excel computations, including those resulting from embedded PyXLL Python functions, are always stored in the Excel spreadsheet. If you disable auto-recalculation, you can share the spreadsheet in read-only mode.
See the File > Options menu, Workbook Calculation (under Formulas in recent versions of Excel) > and select the Manual option.
