Issue #396 resolved
It seems that openpyxl does not write "=" characters when writing workbooks.
Following piece of code highlights the problem:
import openpyxl import os import os.path as osp workbook = openpyxl.workbook.Workbook(optimized_write=True) sheet = workbook.create_sheet() sheet.title = u'hello' sheet.append(['=']) workbook.save(osp.join(os.getcwd(), 'test.xlsx'))
I am using openpyxl 2.1.3 with lxml.
Thanks to have a look,
