Does it support regular expressions?

Yes — enable the regex option to use patterns and capture groups. With regex off, your search text is matched literally.

How many matches does it replace?

All matches are replaced at once, and a live count tells you how many replacements were made.

Can I use capture groups in the replacement?

Yes, with regex mode on. Wrap part of your pattern in parentheses and reference it in the replacement with $1, $2 and so on. For example, find (\\w+)@ and replace with $1[at] to rewrite email handles.

How do I match across line breaks or whole words only?

Use regex mode. \\b marks a word boundary so cat does not match cats, and patterns like .* match within a line. Enable case-insensitive matching to ignore upper/lower case.

Is my text sent to a server?

No — find and replace runs entirely in your browser and nothing is uploaded.

What is the Find and Replace Text?

Free find and replace tool — swap every occurrence of a string or regular expression in your text, with case-insensitive and regex options and a live replacement count. Runs entirely in your browser, nothing is uploaded. It runs free in your browser on Gera Tools, with nothing uploaded.

Find and replace text

Cleaning up a document, renaming a term across a code snippet, or reformatting pasted data all come down to the same task: swap every occurrence of one string for another. This tool does bulk find-and-replace on any text you paste, with an optional regular-expression mode for patterns the simple version cannot reach, and a live count of how many replacements it made.

How it works

Paste your text, type what to find and what to replace it with, and the result updates instantly. With regex off, the find value is matched literally — every exact occurrence is swapped. With regex on, the find value is treated as a JavaScript regular expression, so you can use character classes, anchors, word boundaries and capture groups (referenced as $1, $2 in the replacement). The case-insensitive toggle ignores letter case while matching. All matches are replaced in one pass and the replacement count tells you how many were made.

Worked examples

Literal replace. Find colour, replace color in a paragraph: every colour becomes color and the count shows the total swapped. Case-insensitive mode would also catch Colour and COLOUR.

Reformatting dates. Turn ISO dates like 2026-05-30 into UK style 30/05/2026:

Find (regex on): (\d{4})-(\d{2})-(\d{2})
Replace: $3/$2/$1

Collapse extra whitespace. Replace multiple spaces or tab runs with a single space:

Find (regex on): \s+
Replace: (one space)

Whole-word replacement. Replace cat without touching catch or scat:

Find (regex on): \bcat\b
Replace: dog

Mode	Find	Replace	Example result
Literal	colour	color	”the color is nice”
Case-insensitive	hello	hi	”Hi World” → “hi World”
Regex	`\s+`		collapses whitespace runs
Regex + capture	`(\w+)@(\w+)`	`$1[at]$2`	obfuscates email domains

Practical guidance

Common mistakes. A literal search is case-sensitive by default, so the will not match The unless you enable case-insensitive mode. In regex mode, characters like ., *, (, and + have special meaning — if you want to match a literal period or parenthesis, escape it: \. or \(.

Capture groups in replacements. Wrap part of your pattern in ( ) and refer to it as $1, $2, etc. in the replacement field. For example, find "(.*?)" and replace with «$1» to change all double-quoted phrases to guillemets.

Count sanity-check. The replacement count appears after the operation. A count of zero when you expected matches usually means the find text is wrong — check for trailing spaces, case mismatches, or an unescaped special character.
