Frequently Asked Questions
What is JSON vs CSV?
CSV is plain text, comma-delimited rows. JSON is structured with keys and values, better for nested data and APIs.
How are headers handled?
First CSV row becomes JSON keys. Each subsequent row becomes an object with those keys.
What about data types?
CSV converts strings by default. Numbers, booleans, nulls may need post-processing in JSON.
Can I convert back to CSV?
Yes, JSON can be converted back to CSV, though nested structures may lose some complexity.
