Free Online Find and Replace Text
This browser-based tool helps you search for specific words, phrases, or complex patterns and then replace, highlight, count, or remove matches in an instant. You can choose from six specialized sub-tools depending on your workflow, whether you need plain-text replacement, regex pattern matching, or bulk editing with multiple pairs. Simply paste your content into the editor or drag and drop files directly onto the workspace to get started. Because every operation runs locally, your data remains completely private and never leaves your device.
Find & Replace
Search for a text string and replace every occurrence with a new string. Supports case-sensitive and whole-word matching.
Regex Replace
Use JavaScript regular expressions with capture groups, quantifiers, and backreferences for pattern-based text transformations.
Bulk Replace
Define multiple find-and-replace pairs and apply them all at once in a single sequential operation.
Count Occurrences
Count how many times a word or phrase appears in your text with case-sensitive and whole-word options.
Find & Highlight
Visually highlight every match with a yellow background to scan large documents quickly.
Find & Remove
Delete every occurrence of a word or phrase from your text. A shortcut for replacing with an empty string.
Online Find and Replace Text with Regex and Bulk Support
When standard text editing tools fall short, this workspace provides six powerful ways to search and modify your content. Use the left panel to configure your search terms, case sensitivity, and whole-word matching options. You can track changes in real-time as the center panel displays your input and the right panel updates with the results. Adjust your workspace layout at any time using the draggable divider between the panels for a comfortable editing experience.
Upload Text Files for Processing
Getting your content into the tool is easy: paste text directly, drag a file into the window, or use the Upload File button. The application supports a wide range of formats, from standard .txt and .csv files to code such as .json, .js, and .css. Since all processing is handled locally, you don't have to worry about file size limits or data security. Your documents stay on your machine.
Case Sensitivity and Whole-Word Matching
Fine-tune your results using the matching precision toggles in the options panel. Enabling case-sensitive mode ensures the tool distinguishes between "Error" and "error," while whole-word matching prevents partial matches, such as finding "log" inside "catalog." These settings work seamlessly across every sub-tool for consistent results.
Regex Replace, Bulk Pairs, and Occurrence Counting
For more advanced tasks, the Regex Replace tool supports full JavaScript regular expression syntax. You can leverage capture groups, character classes, and lookaheads to perform complex transformations like reformatting dates or stripping HTML tags. The replacement field also supports backreferences such as $1 and $2, making it easy to rearrange data exactly how you need it.
Bulk Replace for Batch Editing
The Bulk Replace feature allows you to manage multiple find-and-replace operations at once. Each pair in your list is processed sequentially, meaning later replacements can act on text already changed by previous steps. Simply click "+ Add Pair" to expand your list or use the X button to remove entries. This workflow is perfect for standardizing terminology or cleaning up large datasets in one go.
Count and Highlight Matches
Use the Count Occurrences tool to see the total number of matches at a glance without modifying your original text. If you need to see exactly where terms appear, the Find & Highlight sub-tool wraps every match in a yellow background within the result panel. This visual aid is especially helpful for scanning long documents to verify pattern placements before making final changes.
How to Use Find and Replace Text
Begin by loading your content into the input panel via pasting, uploading, or dragging a file. Once your text is ready, select the appropriate sub-tool from the sidebar and enter your search terms. You can then toggle matching options like case sensitivity before clicking the action button to process the text. The right panel will display your results with clear indicators of what changed, allowing you to copy the output or download it as a text file.
Visual Diff for Replacements
Both the Find & Replace and Regex Replace tools feature a visual diff in the results panel to help you review changes. Deleted text is marked in red strikethrough while new text appears in green, giving you total confidence in the accuracy of your modifications before you finalize the document.
Find & Remove for Text Cleanup
When you need to strip unwanted content entirely, use the Find & Remove sub-tool to delete every match from your text. This tool simplifies the process by removing the replacement field altogether, making it ideal for cleaning up tracking parameters, repeated phrases, or any other clutter in your data.
Your Text Stays Private in Your Browser
Privacy is a core feature of this tool, as every operation runs entirely within your browser using native JavaScript engines. Your text is never transmitted to a server, stored in a database, or tracked by external services. Once you close the tab, your data is gone, and you can enjoy full access without registration, cookies, or usage limits.
