Frequently asked questions

How do I find and replace text in bulk?

Paste your text, type what to find and what to replace it with, and the result updates immediately with the number of replacements. Every match is replaced at once, and the Copy button copies the new text. Your original text in the box is not changed.

Is find and replace case-sensitive?

Not by default. It matches the word in any capitalisation, so the finds The, the and THE. Turn on Match case to only replace exact matches. The replacement is inserted exactly as typed and does not copy the capitalisation of the matched text.

How do I use regex in find and replace?

Turn on Regular expression, then use standard JavaScript patterns. In the replacement, $1, $2 and so on insert captured groups and

amp; inserts the whole match. For example, finding (\w+)@(\w+) and replacing with $2 at $1 rearranges the parts. Invalid patterns show an error.

What does the Whole word option do?

It only matches the search term when it stands alone as a word. Searching for cat with Whole word on leaves concatenate and category unchanged, while replacing the separate word cat. It works with regular expressions too.

Why does ^ or $ only match the start or end of the whole text?

The search does not use multiline mode, so ^ and $ anchor to the start and end of all your text, not to each line. To work with line breaks, match them directly with \n in regex mode. Line-by-line clean-up may be easier with the Remove Spaces tool.

How do I replace special characters like a dot or parenthesis?

Leave Regular expression off and type the character as it is. In normal mode everything is matched literally, so a full stop, dollar sign or bracket is treated as plain text. You only need to escape special characters with a backslash when regex mode is on.

Is my data shared when using the Find & Replace?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.
