Acerca de Find and Replace

This tool finds a string or pattern across a block of text and replaces every occurrence at once — handy for renaming identifiers, cleaning up logs, or unifying terminology in a draft. Beyond plain literal matching, it supports regex patterns (with `$1`-style capture group references), case sensitivity, and whole-word (`\b`) matching. The replacement count updates live as you type. In regex mode, an invalid pattern shows an error message and no replacement is applied.

Cómo usarla

  1. Enter the find and replace strings
  2. Toggle regex, case sensitivity, or whole-word as needed
  3. Copy the result

Preguntas frecuentes

Can I use regex capture groups?

Yes. In regex mode, write `$1`, `$2`, etc. in the replacement to reference capture groups.

What does whole-word matching mean?

Searching for “cat” won't match inside “catalog” — only the standalone word “cat” is replaced.

Is my text sent anywhere?

No. Find and replace runs entirely in your browser; nothing is sent to toco.tools servers.
