Find and Replace Text — Free Online Tool
What is Find and Replace Text?
The Find and Replace tool is an advanced string manipulation utility that searches your text for a specific sequence of characters and instantly swaps it with new text. It is the most powerful tool for bulk-editing documents, whether you are updating pricing in a catalogue, changing character names in a manuscript, or substituting outdated URLs in HTML code.
Unlike the basic find-and-replace feature in standard word processors, this tool also supports regular expressions (regex), allowing developers and power users to perform complex, pattern-based substitutions.
When to use Find and Replace Text?
Use this tool for bulk edits. Writers use it to standardize terminology or swap names centrally.
Data analysts use it to clean up CSV files. If you need to quickly remove all messy spaces, you could execute a Regex replace, though our dedicated Remove Extra Spaces tool is much faster.
How to use this tool
- 1Paste your text
- 2Enter the search term and replacement
- 3Choose options (regex/case-sensitive) and click 'Replace'
Always preview your output. A simple find-and-replace for the word 'he' will also accidentally replace the 'he' inside the word 'there', ruining your text unless you match whole words only or use Regex boundaries (he).
Examples
| Input | Output |
|---|---|
| 'color' → 'colour' in 500 words | All instances replaced + count shown |
| Regex: \d+ → [NUMBER] | Replaces all numbers with [NUMBER] |
| ' ' (double space) → ' ' (single) | Fixes double spaces throughout |
| [PLACEHOLDER] → 'Company Name' | Template variable substitution |
| old-api-url → new-api-url | Bulk URL replacement in docs |
Rules & Behavior
- Standard literal mode looks for exact string matches without evaluating context.
- Case-sensitivity can be toggled to strictly target matching capitalizations only.
- Regex mode enables pattern matching (e.g., d+) so you can replace abstract variables rather than explicit words.

Frequently Asked Questions
What does Find and Replace actually do?
It scans an entire document for a specific word (the 'Find' field) and instantly overwrites every instance of it with new text (the 'Replace' field). It turns hours of manual editing into a one-second batch operation.
Why did it ruin words I didn't mean to change?
A basic find-and-replace is literal. If you tell it to replace 'he' with 'they', it will perfectly change 'he is here' into 'they is theyrey'. To avoid string collisions, make sure you match whole words, or use our Plain Text Converter to clean the formatting first.
What is Regex mode?
Regex (Regular Expressions) is a complex pattern-matching syntax used by programmers. Instead of searching for literal words, Regex allows you to find abstract patterns—like 'find any 4-digit number'—and manipulate them cleanly.
Can I replace a word with nothing?
Yes. To instantly bulk-delete a specific word or character from your document, just type the target text in the 'Find' box and leave the 'Replace' box entirely empty. The system will scrub it clean, similar to the Remove HTML Tags utility.
Is the replacement case-sensitive?
Standard tools offer a toggle. If case-sensitive is OFF searching for 'apple' will also replace 'Apple'. If case-sensitivity is ON, searching for 'apple' will ignore 'Apple'. Always review your assumptions before committing a bulk edit.
