Python and openpyxl is saving my shared workbook as unshared

问题

Using Python and openpyxl I have a code that goes into a workbook, adds a bunch of information to some cells every day, and then closes and saves it. My problem is that if this workbook is open the code doesn't work (obviously).

By making the workbook shared(multiple users can edit at once) I can overcome this problem, however after the code runs once, python saves and then reverts it back to a closed, unshared workbook. Anyone know if openpyxl can save as shared? I'm not finding anything online. Pre-emptive thanks for your help.

It seems that when openpyxl saves an Excel workbook, the docProps/app.xml file inside is wiped and contains only minimal information.

A quick (and dirty) solution is to use zipfile to get these information and transfer them into the new/saved file.

import zipfile, openpyxl

def shared_pyxl_save(file_path, workbook):
    """
    `file_path`: path to the shared file you want to save
    `workbook`: the object returned by openpyxl.load_workbook()
    """
    zin = zipfile.ZipFile(file_path, 'r')
    buffers = []
    for item in zin.infolist():
        buffers.append((item, zin.read(item.filename)))
    zin.close()

    workbook.save(file_path)

    zout = zipfile.ZipFile(file_path, 'w')
    for item, buffer in buffers:
        zout.writestr(item, buffer)
    zout.close()
