How does ordering work?

Rows run top-to-bottom. The output of row 1 is the input to row 2. This means later rows can match strings introduced by earlier rows — useful for chained transformations, but also a footgun if not intended. Reorder rows to control overlap.

What regex flavor does this use?

ECMAScript (browser/Node.js). Special characters like `.`, `*`, `+`, `?`, `(`, `)`, `[`, `]`, `{`, `}`, `\`, `|`, `^`, `$` need escaping when matched literally. Use named or numbered capture groups in the find field; reference them with `$1`, `$2`, or `$ ` in the replace field.

Plain text vs regex — when to choose?

Plain text is safer and faster for literal substitution: 'Smith' → 'Jones'. Regex is needed for patterns: matching numbers, optional spaces, repeated chars, or anchored start/end of line. If you're not sure, start with plain.

Is replacement done globally?

Yes. Each row replaces ALL occurrences in the current text. To replace only the first, prefix the find pattern with `(?:[^...]*?)` regex tricks — or just paste a single occurrence into the input.

What about whole-word match?

Use regex mode and wrap your term in `\b...\b` word-boundary anchors. Example: find `\bcat\b` won't match 'concatenate' or 'cats'.
