- People reviewing revised inventory or order spreadsheets
- Worth noticing
- Blank or duplicate IDs stop the comparison; the tool will not guess which records correspond.
Field notes
The workflow requires a worksheet and identifier column in each file; headers must be non-empty and unique, and fully empty rows are ignored. The page gives a worked inventory example and explains that moving a row does not count as an edit. Its stated limits include one million combined cells, and malformed or unsupported files are rejected.
