Frequently Asked Questions
How does CSV to JSON work?
The first row becomes JSON object keys. Each subsequent row becomes one JSON object with values mapped to the corresponding keys, resulting in a JSON array.
What delimiters are supported?
Comma (,), Semicolon (;), Tab (\t) and Pipe (|). Select the correct delimiter matching your CSV file.
Can I convert TSV files?
Yes. Select Tab as the delimiter to parse tab-separated value files correctly.
Is there a size limit?
No strict limit. The converter runs in your browser. Very large files (over 10MB) may process more slowly.
