FindSwap
Find and replace for Google Docs that shows every match first.
Type what to find and what to replace it with, click Find, and FindSwap lists every match with the words around it. Untick anything you want to keep, click Replace, and undo anytime. Works across every tab, headers, footers, footnotes and tables, with match case, whole words and regex.
One-click clean-up fixes double spaces, extra blank lines, quotes, dashes and more.
Free: find, preview, replace, regex, clean-up and undo, with no trial and no limits. Pro: $4/month or $24/year to replace whole lists at once, replace as suggestions (tracked changes), replace with or find by formatting, keep case, and run on other Docs.
