I'm trying to generate spreadsheets in different formats that contains formulas.

However, different formats have produced different result.

For example:

import pyexcel

sheet = [['=HYPERLINK("https://www.google.com", "Google")']]

pyexcel.save_as(array=sheet, dest_file_name="test.xlsx")
pyexcel.save_as(array=sheet, dest_file_name="test.ods")
pyexcel.save_as(array=sheet, dest_file_name="test.xls")

The output files can be splitted into two groups:

• Treat formula as string (with ' added in front): ods and xls
• Treat formula as formula: xlsx

It's quite close to #8, but that seems focusing on loading data from xlsx file. AFAIK, data_only for the openpyxl.workbook.Workbook class is a read-only property.

Is there any flag for pyexcel.save_as and pyexcel.save_book_as function that can correctly write formula based on developer's requirement?

For example, auto_detect_formula=True will write strings starting with = as formulas, while auto_detect_formula=False will treat all all strings as strings.

Here's the environment I'm currently using, if it helps:
