Find & Replace
Find and replace text with regex, case, and whole-word options.
The Find & Replace tool is an indispensable online utility designed to streamline text modification tasks. Whether you're a developer needing to update variable names across a codebase, a content creator standardizing product terminology, or a data analyst cleaning raw data, this tool offers precise control over your text. Simply paste your document, script, or data block into the input area. You'll then specify the exact text or pattern you wish to locate, and what you want to replace it with.
This powerful utility shines with its advanced options. Leverage regular expressions (regex) to search for complex patterns, such as all email addresses, specific date formats, or numerical sequences, and effortlessly transform them. For instance, you could quickly change "YYYY-MM-DD" to "DD/MM/YYYY" across an entire dataset. The case-sensitive and whole-word matching options provide granular control, preventing unintended alterations. For example, replacing "cat" as a whole word won't affect "category." The output is your modified text, ready for immediate use. A useful tip for complex regex patterns: always test them on a small sample of your text first to ensure they behave as expected before applying them to your entire document.

Frequently Asked Questions
What is regex and how can I use it with Find & Replace?
Regular expressions (regex) are sequences of characters that define a search pattern. When enabled, Find & Replace can use these patterns to locate and manipulate complex text structures, like reformatting all phone numbers or extracting specific data elements.
Can I perform a case-insensitive search?
Yes, by default the tool performs a case-sensitive search. To make your search case-insensitive, simply uncheck the 'Case Sensitive' option.
What happens if my replacement string contains the search string?
The tool will replace the found instance of the search string with your entire replacement string. It won't recursively find and replace within the newly inserted replacement text in a single operation.
Is there a limit to the amount of text I can process?
While typically generous, extremely large text inputs (many megabytes) might experience performance slowdowns or browser limitations. For optimal performance, consider splitting very large files.
When should I use 'Whole Word' matching?
Use 'Whole Word' matching when you want to ensure that only complete words are replaced. For example, replacing "man" with "person" would only affect "man" as a standalone word, not occurrences within words like "manual" or "manager".
Does this tool save my data or text?
No, this tool processes all your text directly in your browser. Your input and output text are never sent to a server, ensuring your data remains private and secure.
