CSV, JSON & XML Converter: Convert Between Any Two Formats, Free

The Free Online Tool That Converts Between CSV, JSON, and XML — Any Direction

If you've ever needed to turn a spreadsheet export into an API payload, or flatten an XML feed into something a database can ingest, you know the pain: most "converter" tools online only handle one direction, choke on nested data, or mangle special characters. Nutilz's CSV, JSON & XML Converter is a free, no-signup tool that handles all six conversion directions between these three formats — and does it with real parsers, not regex hacks.

What it does

The tool converts between CSV, JSON, and XML in any direction: CSV → JSON, CSV → XML, JSON → CSV, JSON → XML, XML → CSV, and XML → JSON. You pick a source format and a target format, paste your data in, and the output updates automatically as you type.

A few details make it more reliable than a quick script you'd write yourself:

• Real parsing, not string manipulation. Quoted CSV fields with embedded commas, nested JSON objects and arrays, and XML attributes are all handled correctly instead of breaking on edge cases.
• Configurable CSV delimiter. Comma, semicolon, tab, or pipe — useful since a lot of "CSV" exports in the wild aren't actually comma-separated.
• Smart XML structure detection. When converting XML to CSV or JSON, the tool looks for repeated child elements (like multiple <item> or <book> tags) and treats each one as a row, so real-world XML that doesn't follow a strict <root><item> convention still converts correctly.
• Attributes preserved. XML attributes such as <book id="bk101"> come through as fields prefixed with @ (e.g. @id), so no data is silently dropped.
• Nested data doesn't break CSV. CSV has no concept of nested objects — when a JSON field contains a nested object or array, it gets stringified into that cell instead of losing the data.
• Swap button. Reverse the conversion direction with one click and reuse your current output as the new input — handy for checking a round-trip conversion.
• Copy or download. Grab the result straight from the page or download it as a .csv, .json, or .xml file.

Conversion runs server-side for accuracy, but nothing is logged or stored — data is processed in memory and discarded immediately after the response comes back.

How to use it

1. Pick the "From" format that matches your input, and the "To" format you need.
2. Paste your data into the input box, or click "Try sample" to see it working with example data first.
3. If CSV is involved on either side, choose the right delimiter.
4. The converted output appears automatically after a short debounce — no button to click.
5. Copy the result or download it as a file.

Why it's useful

This kind of conversion comes up constantly in everyday dev and data work:

• Migrating data into an API. Product or customer data often starts life in a spreadsheet (CSV) but needs to be posted to a REST API as JSON.
• Working with legacy XML feeds. RSS/Atom feeds, SOAP responses, and older enterprise systems still speak XML — converting to JSON or CSV makes that data usable in modern JavaScript apps or spreadsheets.
• Debugging data pipelines. Quickly eyeballing what a JSON export looks like as a flat CSV table (or vice versa) is often faster than writing a one-off script.
• Non-developers who need a spreadsheet. Someone on a data or ops team who's handed a JSON or XML file can turn it into CSV and open it directly in Excel or Google Sheets, no code required.
