Find and Replace Bulk

Yes, rule order matters because the rules run sequentially in All Rules mode: the output of one rule becomes the input for the next, so a later rule sees text that earlier rules already changed. This means a broad rule can swallow text a narrow rule was meant to catch, or two overlapping rules can chain in ways you did not intend. The safe habit is to put broad or general changes before narrow ones when they could touch the same words, and to test the chain in Step-by-Step mode, which applies one rule at a time so you can watch exactly what each step does. Drag your rules into the right sequence, then use the live match counts on each rule to confirm every pattern is hitting the text you expected before you copy the final result.

A plain find matches your term anywhere it appears, including inside longer words, so replacing "cat" would also alter "category" and "concatenate." Turning on Whole word wraps the term in word boundaries, so only the standalone word "cat" is matched and the surrounding text is left untouched. This is the key option when you are swapping a short or common substring that could accidentally appear inside other words, such as renaming a variable, fixing a single misused term, or replacing a name without mangling similar strings. Whole word is a per-rule switch, so you can enable it on the rules that need precision while leaving other rules to match freely. Add a rule, type your term, toggle Whole word on, and the live match count shows exactly how many true word matches it found.

Use the Export button to save your entire current rule set — every find, replace, and the case-sensitive, whole-word, regex, and enabled settings for each rule — as a single JSON file. Later, or on another machine, the Import button loads that file back so all your rules return exactly as you built them. This turns a one-off cleanup into a reusable recipe: a house-style spelling sheet, a redaction set that masks emails and URLs, or a migration script that rewrites old paths to new ones. Because the rules are plain JSON, you can also store them in version control or share the file with a teammate so everyone applies the same transformations. Build your rules once, click Export to keep them, and Import them whenever you need that same set of changes again.

When you enable Regex on a rule, the find field is treated as a JavaScript regular expression rather than literal text. If that pattern is malformed — an unclosed bracket, a stray quantifier, or an unbalanced group — the tool cannot compile it, so that single rule shows an inline error badge and is skipped rather than breaking the entire run. Your other valid rules still apply normally, which keeps a typo in one pattern from wrecking the whole pass. To fix it, check the flagged rule for syntax issues, or if you meant to match the characters literally, turn Regex off so symbols like dots and parentheses are matched as plain text. Correct the pattern and the error badge clears, after which the rule rejoins the run and its match count updates to show what it found.

Yes. Switch to Step-by-Step mode to apply one rule at a time and watch the text change between each step, which is the fastest way to debug a chain of substitutions or confirm exactly which rule produced an unexpected result. A Restart button rewinds to your original input so you can replay the sequence as many times as you like. Every rule also shows its own live match count, and a counter at the top reports the total rules, how many are enabled, the total replacements made, and how many rules actually changed anything — so you can spot a rule that matched nothing or one that matched far more than expected. Run through your rules step by step first, verify each result, then switch to All Rules mode to apply the full set in one pass.
