Frequently Asked Questions — JSON to CSV Converter
What JSON structure works best for CSV conversion?
An array of objects with consistent keys works best, like [{name: "Alice", age: 30}, {name: "Bob", age: 25}]. Each object becomes a row and each key becomes a column header. The tool handles missing keys by leaving those cells empty.
How are nested objects handled?
Nested objects are flattened using dot notation. For example, {address: {city: "NYC"}} becomes a column named "address.city" with value "NYC." Deeply nested arrays are converted to JSON strings within the cell.
Can I choose a different delimiter instead of comma?
Yes. You can select comma, semicolon, tab, or pipe as your delimiter. Semicolons are preferred in European regions where commas are used as decimal separators. Tab-separated values (TSV) are common for importing into some database tools.
