Frequently Asked Questions

Can I convert nested JSON objects to CSV?
Yes! Enable "Flatten Objects" to convert nested structures like {"user":{"name":"John"}} to columns like "user.name". This makes complex JSON data spreadsheet-friendly.
How are arrays within JSON objects handled?
You can choose to stringify arrays (convert to text), separate them into multiple columns, or ignore them entirely. Stringify is most common for preserving data.
What delimiters are supported?
Common delimiters include comma (,), semicolon (;), tab (\t), and pipe (|). Choose based on your target application and locale preferences.
Can I import the CSV into Excel?
Yes! The generated CSV is Excel-compatible. Use semicolon delimiter for European Excel versions that expect this format by default.
How are null and undefined values handled?
You can choose to leave empty cells, explicitly write "null", or skip null values entirely. Empty cells are most common for spreadsheet compatibility.
