Question 1

How do I find and replace text online?

Accepted Answer

Paste your text, type what to find and what to replace, and the result appears live. The match counter tells you how many replacements were made.

Question 2

Can I replace multiple words at once?

Accepted Answer

Yes — use regex mode with alternation (e.g. cat|dog|fish) to match several terms in one pass. The replacement text applies to every match.

Question 3

Regex (regular expressions) lets you match patterns instead of literal text — like "any digit" (\d), "any word boundary" (\b), or "one or more spaces" (\s+). Toggle Regex mode and pick your flags.

Question 4

How do I replace line breaks with commas?

Accepted Answer

Toggle Regex mode, set Find to 
, and Replace to , (comma). Add the g flag to replace every occurrence.

Question 5

Can I replace only whole words?

Accepted Answer

Yes. Toggle "Match whole words only" so finding "cat" doesn't match inside "category" or "concatenate".

Question 6

How do I replace case-insensitively?

Accepted Answer

Toggle the i flag in Regex mode, or use "Ignore case" in plain mode. Both treat "Hello" and "hello" as the same match.

Question 7

Can I preview replacements before applying?

Accepted Answer

Yes — the result and match count update live as you type, so you see exactly what will be replaced before you copy the output.

Question 8

How do I undo a replace?

Accepted Answer

The original text stays in the input box. Clear the Replace field (or restore the previous Find pattern) to revert — the output box re-renders instantly.

Question 9

Can I replace text in a list of URLs?

Accepted Answer

Yes. Paste the URLs, find a common substring (like an old domain) and replace with the new one. Toggle Regex mode if you need to match a pattern.

Question 10

How do I replace spaces with hyphens?

Accepted Answer

In plain mode, set Find to a single space and Replace to a single hyphen. Or use the Text to Slug tool — it does this automatically.
