Frequently Asked Questions

What JSON structure works best for CSV?
An array of flat objects works best. Each object becomes a row and each key becomes a column header.
Is my data safe?
Yes. Everything runs in your browser. No data is sent to any server.
Can I open the CSV in Excel?
Yes. Download the .csv file and open it directly in Excel, Google Sheets, or any spreadsheet application.
Does it handle nested objects in CSV?
Nested values are serialized as JSON strings in the CSV output to preserve the data structure.
