Find & Replace Text - Online String Replacer Tool
Find & Replace Text
Quickly search and replace text online. Supports case sensitivity, whole word matching, and regular expressions.
Frequently Asked Questions
It is an online utility that lets you search for specific text within a body of content and replace it with another string. You can use plain text or regular expressions, control case sensitivity, and match whole words only.
When enabled, the tool only matches the exact word, not parts of a word. For example, searching "cat" won't match "category" or "scatter". This option is ignored when using regular expressions.
Yes, check the "Use Regex" box and enter a valid regex pattern in the "Find" field. You can utilize flags like /i for case-insensitivity by unchecking "Case sensitive". Note: Whole word is automatically disabled in regex mode.
Currently the tool performs a global replace (all matches). If you need to replace just the first match, you can achieve that with a regular expression and a non-global flag, but in the current version all occurrences are replaced.
