Error writing XLSX output in KiBoM 1.8.0

[KKlim]

The script starts but no xlsx output file is generated. Some bugs are reported.
Other formats such as csv, tsv, txt, html work rather ok and generate output files.

Windows 10 Pro 64bit PL
KiCad version: 5.1.9

Run command:
python "C:_KiCad\KiBoM/KiBOM_CLI.py" -v "C:_KiCad\KiBoM\test\kibom-test.xml" "C:/_KiCad/KiBoM/test/kibom-test.xlsx"

Command error. Return code -1

Do you have the xlsxwriter python module installed?

[KKlim]

After installing the XlsxWriter module, xlsx files are generated.
Thanks for the hint. :-)

I have suggestions that in the documentation, instead of:
XLSX (Needs XlsxWriter Python module)
it was written:
XLSX (Needs XlsxWriter Python module to be installed).

Link to the description of how to install XlsxWriter:
