About the Line-by-Line Comparison

Compare two lists by row number, as you would two columns in a spreadsheet, or as sets: what is in both, what is only in the first, what is only in the second. It answers questions like which emails from last month's list are missing this month, or which source lines a translation skipped.

How to use it

  1. Paste list A on the left and list B on the right.
  2. Pick By position or As sets.
  3. Copy any of the resulting lists.

Questions

How is this different from the diff checker?

The diff checker finds the smallest set of edits between two versions of one document. This tool compares row 1 with row 1, row 2 with row 2, or treats each list as a set. Use it for lists and aligned translations.

Does the order of lines matter in set mode?

No. In set mode, a line counts as shared wherever it appears in the other list.

Can it ignore case and spaces?

Yes, both are options.
