Frequently Asked Questions
Can it handle nested JSON objects?
Yes. Nested objects are flattened with dot notation (e.g., user.name, user.email). Deeply nested structures may require manual adjustment.
What if my JSON is an array vs single object?
Arrays of objects convert to multi-row CSV. Single objects convert to 1-row CSV with object keys as headers.
Does CSV to JSON preserve data types?
Numbers and booleans are inferred. Dates remain as strings (add manual parsing if needed). Empty cells become null.
Can I customize CSV delimiters?
Currently comma-delimited only. For semicolon or tab-delimited, open the CSV in Excel and use 'Save As' with delimiter options.
Is there a row/column limit?
No artificial limits. Browser memory is the only constraint (typically handles 100K+ rows).
