CSV to JSON Converter
Fast, secure, and client-side conversion. Transform standard CSV files into clean JSON objects.
The Developer's Data Knife
Whether you're migrating a database, seeding an API, or just trying to read a massive config file, switching between CSV (Excel-friendly) and JSON (Web-friendly) is a daily task.
Our CSV to JSON Converter is built for speed and privacy. Unlike other tools that might queue your files on a server, we process everything locally.
Pro Features, Free Forever
Privacy First
We use 0% server-side code for conversion. Your data stays in your RAM, making this safe for sensitive work docs.
Smart JSON
We automatically detect numbers and booleans ("true"/"false") so you don't get everything as a string.
Any Delimiter
Working with European CSVs (semicolons) or TSV files? Just select your delimiter and we handle the parsing.
