XL Diff

A dead-simple command line diffing of datasets stored in Excel format (.xlsx).

Usage

python -m xldiff file_left.xlsx file_right.xlsx

If the datasets match then the program will exit successfully and produce no output. If they do not match then the first non-matching row from the "left" and the "right" versions will be printed and the program will terminate with a non-zero exit code.

OK, but what's it for? Mostly to make it easier to verify that data has been moved successfully from one system to another or that a new "version" of a dataset has actually changed.
