Data conversion guide

CSV is simple to exchange, while structured formats are easier to use in applications.

JSON

JSON works well for APIs, JavaScript applications, configuration and document databases.

NDJSON

NDJSON stores one JSON object per line and is useful for streaming and large datasets.

XML

XML is common in enterprise integrations, feeds and systems that rely on schemas.

Type inference

Type inference converts obvious numeric, boolean and null values instead of keeping every value as text.

Frequently asked questions

CSV conversion questions answered.

Does the parser support quoted commas?

Yes. Quoted fields, escaped double quotes and line breaks inside quoted fields are supported.

Can column names create nested objects?

Yes. Enable nested dot keys so a header such as user.name becomes a nested object property.

Can I convert JSON back into CSV?

Yes. Paste a JSON array into the output editor and use the JSON back to CSV action.

Are files uploaded?

No. Conversion is performed locally in the browser.
