What is a batch text replacement tool?

A batch text replacement tool allows you to set up multiple find-and-replace rules at once and run them all in a single click on your target text, instead of running them one by one.

Does the order of replacements matter?

Yes. The replacements are processed sequentially, from top to bottom. This means rule 2 will run on the text that has already been modified by rule 1, allowing you to chain changes.

Can I use Regular Expressions (Regex) in batch replacements?

Yes. You can toggle the Regex option individually for any replacement pair in the list to match complex text patterns, variables, or digits.

How do I save my list of find and replace rules?

You can click the "Export Rules" button to download your rule configuration as a JSON file. To reuse them later, simply click "Import Rules" and upload the same JSON file.

Chained Text Replacements Made Easy

Replacing multiple distinct terms across a large text file can be a frustrating chore if you have to perform them one by one. Our online Batch Replace tool lets you compile a list of multiple find-and-replace rules, configure options for each row, and run the entire chain in a single action.

The rules are applied in sequence. The first rule replaces matching text in your input; the second rule is then applied to the output of the first; and so on. This sequential approach allows you to format data step-by-step or clean up texts dynamically.

How to Configure and Execute Rules

➕ Creating Your Rules List

Click "Add Rule" to append a new find-and-replace row. In the "Find What" input, write the target string you want to search for, and in the "Replace With" input, write the replacement value. You can leave the replacement input blank to delete the matched search term entirely from the document.

⚙️ Individual Rule Options

Every replacement pair in your list has its own set of toggles:

Match Case: Forces the search query to match the capitalization exactly.
Whole Word: Restricts matches to complete words, preventing accidental replacement of partial letter sequences within other words.
Regex: Treats the search query as a JavaScript regular expression, allowing you to use wildcards, character sets, and anchors.

📥 Saving and Loading Rules (JSON)

If you regularly execute the same set of text substitutions, you do not need to retype them every time. Click the "Export Rules" button to download your current list of configurations as a JSON file. When you return to the page, use the "Import Rules" button to restore your replacement list instantly.

Secure and Local Text Processing

Like all our utilities, the batch replacer operates entirely client-side. The replacement operations, JSON configuration parsing, and file handling happen right inside your web browser. No text or rule lists are ever transmitted to external servers, ensuring complete privacy and security for confidential documents, source code, and custom lists.

Frequently Asked Questions

What is the order of execution for batch replacement?

The rules are applied in top-to-bottom sequence. The output text of the first replacement is passed as the input for the next replacement. Keep this in mind, as early replacements can affect the search patterns for subsequent rules.

Can I import a custom JSON file to populate rules?

Yes. The JSON format is an array of objects. Each object should have keys: "find", "replace", "matchCase", "matchWhole", and "useRegex". You can edit the JSON file in any text editor or download it directly using the export button.

How does regex capture groups work in batch replacement?

When you check the Regex option for a rule, you can use capture groups in the "Find" pattern (such as (\w+)) and refer to them using $1, $2, etc., in the "Replace" field, enabling advanced text transformations.

Is there a limit to how many rules I can add?

There is no hard limit. You can add as many rules as you need. Since the processing runs locally in your browser, even lists with hundreds of rules will execute in fractions of a second.
