cell is a programming language for processing Excel files (.xlsx) for the command line.
For example, you can create an Excel file as follows.
$ cell -to greeting.xlsx '["A1"]="Hello, Excel"'
Alternatively, data from an Excel file can be fed into the command pipeline as shown below.
$ cell -from users.xlsx -n 'puts(["A".NER])' | grep twinbird
See the tutorial for details.
Also, see the command help for options.
$ cell -h
You can download from the release page.
Thanks to the Excelize project.
Without Excelize, this project would never have been created.
And many many thank you DeepL.
