Which data formats are supported for bidirectional conversion?

The Universal Data Converter bidirectionally converts between JSON, YAML, XML, CSV, TSV, and TypeScript interfaces in a single unified view.

Is my data uploaded to any remote server?

No. The AST parser and multi-format serializers execute 100% locally inside your web browser. Test in Airplane Mode to verify zero network requests.

Why One Universal Converter is 10x Faster

Developers, data engineers, and technical writers constantly move data across incompatible formats:

API Payloads: JSON from REST endpoints ➔ YAML for Kubernetes / GitHub Actions.
Legacy Systems: SOAP / XML enterprise feeds ➔ Modern JSON objects.
Spreadsheets: CSV / Excel exports ➔ Structured JSON arrays or TypeScript models.

Instead of opening 4 separate browser bookmarks (JSON to YAML, YAML to XML, CSV to JSON), the Universal Data Converter parses your input once and renders all corresponding representations in a single synchronized viewport.

Frequently Asked Questions

How does the automatic format detection work?

The engine analyzes opening characters, syntax tokens, and structural AST signatures ({}, , key: value, comma delimiters) to identify whether the input is JSON, XML, YAML, or CSV.

Can it convert nested JSON to CSV?

Yes. When an array of objects has nested properties, objects are safely flattened and serialized into stringified CSV columns.
