Convert API JSON into CSV or a Markdown table.
Turn spreadsheet-style CSV into JSON, XML, or SQL inserts.
Move simple configuration data between YAML, TOML, and JSON.

Supported formats and shapes

The converter supports JSON, CSV, YAML, XML, TOML, SQL insert statements, Markdown tables, and HTML tables. Tabular formats work best with arrays of objects that share consistent fields.

Review complex conversions

These formats do not represent every data type in the same way. Nested objects, null values, mixed arrays, attributes, comments, and advanced syntax may need manual adjustment after conversion.

Frequently asked questions

Does conversion happen locally?

Yes. Parsing, conversion, copying, and file creation happen in your browser.

Why does a table conversion lose nested structure?

CSV, Markdown tables, HTML tables, and SQL rows are flat by nature. Nested JSON, YAML, XML, or TOML may need to be flattened first.

Can the tool detect a format automatically?

A loaded file can select a format from its extension. For pasted text, choose the source format explicitly.
