Frequently asked questions
How are nested objects handled?
Turn on Flatten nested objects and every nested value becomes its own column using dot notation, for example address.city. Arrays use numbered columns like tags.0 and tags.1.
Are commas and quotes inside values escaped correctly?
Yes. Any value containing the delimiter, a quote or a line break is wrapped in quotes with inner quotes doubled, following RFC-4180, so Excel and Google Sheets open the file cleanly.
Is this tool really free?
