Add Line Numbers workflow tips

Use this tool when a plain list needs reference numbers before review, publishing, QA, documentation, or spreadsheet handoff.

Clean before numbering

Run Trim Lines, Remove Empty Lines, or Remove Duplicate Lines before adding numbers to a messy list.

Undo numbering later

If a copied list already has prefixes, switch to Remove Line Numbers before sorting, joining, or comparing the text.

Reshape numbered lists

After numbering, use Prefix / Suffix Lines, Sort Lines Alphabetically, or Line Counter when the list needs another pass.

  3. Copy the numbered output into docs, spreadsheets, review comments, checklists, or another text cleanup workflow.
