Formatters
Format and beautify code, data, and text. — 5 tools available.
Formatter tools help you clean up raw, minified, or machine-generated data so it becomes readable to humans. Whether you have a collapsed JSON string from an API response, an unindented configuration file, or XML output from a legacy system, a formatter applies consistent indentation and structure in one click. All formatting runs locally in your browser — paste your data, click format, and copy the result. No server ever sees your payload.

Frequently Asked Questions
What does a code formatter do?
A code formatter takes raw, minified, or inconsistently indented code and applies a consistent structure with proper indentation, line breaks, and spacing. This makes the code easier to read, debug, and maintain. Formatters work on structured data formats like JSON, XML, HTML, CSS, and SQL. The formatting is purely cosmetic — the data content stays identical; only the whitespace and line structure changes.
Does formatting my data change its content?
No. Formatting only changes whitespace, indentation, and line breaks. The actual data values, keys, and structure remain identical. A minified JSON string and its pretty-printed version parse to exactly the same object. You can safely format data for readability and then minify it again for production use without any data loss.
Is it safe to paste sensitive data into an online formatter?
It depends on the tool. Formatters that send your data to a server for processing expose your input to network interception and server-side logging. UtilDaily's formatters run entirely in your browser using JavaScript — no data is transmitted to any server. You can verify this by checking the Network tab in your browser's DevTools while using the tool.
