Find and replace without the regex learning curve

Regular expressions are powerful and genuinely hard: getting a pattern subtly wrong silently mangles text, and most people need find-and-replace a few times a month, not daily. Plain literal replacement — find this exact string, put that one in its place — covers the overwhelming majority of real tasks with zero risk of a pattern misfiring on text you did not anticipate.

This tool does literal matching, with case sensitivity as an explicit choice. Turning case sensitivity off is what you want when replacing a name that appears capitalized at the start of sentences and lowercase mid-sentence; turning it on matters when "IT" the department must not become "it" the pronoun.

Techniques that make replacement safer

Match more than you think you need. Replacing "cat" with "dog" also turns "category" into "dogegory" and "concatenate" into "condogenate" — the classic Scunthorpe-style failure. Including the surrounding spaces (" cat " for " dog ") or replacing whole phrases avoids it. Similarly, replacing "a" with "the" across a document is almost never what anyone wants.

For multi-step edits, work from most specific to least specific. If you are changing "New York City" to "NYC" and also "New York" to "NY", do the longer one first — otherwise the first pass turns your target into "NY City" and the second never matches. And because replacement is instant and non-destructive here, testing on a paragraph before pasting the whole document costs seconds and catches these traps early.
