Frequently asked questions

Questions about JSON to CSV Converter

What JSON format works best?

An array of objects works best because object keys become CSV columns. Arrays of simple values are also supported and are written as one value per row.

What happens if objects have different keys?

The converter combines all keys found across the array into the CSV header. Missing values are left blank for records that do not contain a particular key.

Does it handle commas and quotes inside values?

Yes. Fields containing the selected delimiter, double quotes, or line breaks are wrapped in quotes, and embedded double quotes are escaped according to CSV conventions.

Is my JSON uploaded anywhere?

No. Conversion happens locally in your browser, so Avorqin does not need to send your JSON to an external API.
