Spreadsheet Cleanup

Fixes inconsistent names, dates, and duplicates in a spreadsheet, and tells you what it changed.

The classic problem: the same organisation spelled four ways, dates in three formats, and rows that are almost but not quite duplicates. This skill standardises all of it and produces a change log so you can check its work.

It never overwrites your original file. You get a cleaned copy alongside it.

What it needs

  • A spreadsheet file
  • Permission to write a new file in the same folder
  • Free.
