Frequently Asked Questions
Does it detect delimiters automatically?
Yes, the tool automatically detects commas, semicolons, tabs, and pipe delimiters. You can also manually specify the delimiter if needed.
How are headers handled?
If 'First row is header' is enabled, the first row becomes JSON keys. Otherwise, rows are converted to arrays.
What about data types?
Numbers and booleans are automatically detected and converted to their proper JSON types instead of strings.
Can I handle large CSV files?
Yes, the tool efficiently processes files up to 50MB. All parsing happens in your browser using the Papa Parse library.
What if my CSV has inconsistent columns?
The parser handles missing values gracefully, inserting null or empty values where needed.
