Which formats are supported?

JSON, YAML, TOML, XML, CSV, and INI. You can convert any format to any other format bidirectionally.

How does format auto-detection work?

The tool analyzes the content patterns automatically: JSON starts with { or [, XML starts with <, YAML has key:value pairs, TOML uses [section] headers, INI uses key=value lines, and CSV has comma-separated columns.

Is my data uploaded anywhere?

No. All parsing, validation, and conversion happens entirely in your browser. Nothing is uploaded to any server.

What happens to XML attributes when converting to JSON?

XML attributes are preserved under an @attributes key on their parent object, and text content is kept under #text.

Can I convert a single object or array to CSV?

Yes. If you convert from JSON to CSV, the tool will create CSV rows from an array of objects. A single object becomes a one-row CSV with a header.

What is Data Converter Hub?

The Data Converter Hub is a unified interface for converting between six structured data formats commonly used in development and configuration: JSON, YAML, TOML, XML, CSV, and INI. Pick any source and target format, paste your data, and get instant results.

It features auto-detection of the source format so you can start typing without selecting a format first. The swap button exchanges source and target formats to flip the conversion direction. Syntax errors are shown inline with the specific parser message to help you debug malformed input quickly.

All parsing and serialization happens entirely in your browser — nothing leaves your device. No uploads, no servers, no data retention.
