Unmerge every cell in an Excel worksheet using openpyxl

Question

Is there a way to unmerge every cell in an Excel worksheet using openpyxl. There isn't a guarentee that every or any cell is merged, but basically I want to unmerge cells if they exist in a worksheet.

Answer 1

You can iterate through the worksheet's merged_cells attribute and use each one as an argument to unmerge_cells() . unmerge_cells() either takes the starting and ending rows and columns, or a range string, but the latter is easier to use by converting the value(s) from merged_cells to a str .

As an example:

>>> ws.merged_cells
<MultiCellRange [A2:A4 A8:D11]>

for merge in list(ws.merged_cells):
    ws.unmerge_cells(range_string=str(merge))

>>> ws.merged_cells
<MultiCellRange []>

( ws.merged_cells doesn't seem to like being iterated while you're unmerging, so list() avoids any issues)
