Frequently Asked Questions
What JSON structure does this support?
The input should be a JSON array of objects where all objects share the same keys. Those keys become the CSV column headers.
How are commas inside values handled?
Values containing commas, quotes, or newlines are automatically wrapped in double quotes and escaped per the CSV standard (RFC 4180).
Is my data uploaded anywhere?
No. All conversion and the table preview happen entirely in your browser.
