How to find and replace a substring across a block of text

1. Paste the text

   Drop the source text into the "Text" field. There's no size limit beyond the form's payload limit; multi-megabyte input works fine for a one-off scrub.

2. Set Find and Replace

   "Find" is what you're searching for — literal characters, NOT a regex (so `.`, `*`, `[` are matched as themselves). "Replace" is what each match becomes. Empty Replace deletes every occurrence.

3. Press Run

   Result returns a single `text` field with EVERY occurrence replaced (it's `String.replaceAll`-equivalent, not a one-off swap). Case-sensitive by default — `Foo` won't match `foo`.

4. When you need regex

   This tool intentionally avoids regex to keep `.` and `*` literal — safer for replacing things like "a.com" or "v1.2" without surprises. For pattern-based replacements use a code-side regex; here, every character is itself.
