CSV to JSON
Convert tabular CSV data into structured JSON objects or arrays. Features automatic delimiter detection, quote unescaping, and intelligent numeric and boolean type inference.
Smart delimiter detection and type inference
Whether your CSV uses standard commas, European semicolons, or tab separators, FileKinetix detects the delimiter automatically. It also intelligently converts numbers (e.g. 42.5) and booleans (true/false) into native JSON types rather than plain strings.
Private, fast, and scalable
Convert customer records, product catalogs, and data dumps into JSON without uploading sensitive spreadsheets to third-party servers.
How to convert CSV to JSON
- Paste your CSV data into the input box or upload a .csv file.
- Check 'First row is header' if your CSV starts with column titles.
- Toggle 'Parse numbers & booleans' to enable automatic type casting.
- Click 'Convert to JSON' to generate structured JSON output.
- Copy the JSON or click 'Download .json' to save it.
Frequently Asked Questions
How does the tool handle commas inside quoted text?
The parser adheres to RFC 4180 rules, correctly treating commas and line breaks inside double quotes as content rather than field separators.
Can I convert CSV without headers?
Yes. Simply uncheck 'First row is header' to output an array of string/number arrays.
Is there any file upload limit?
Because all parsing is executed locally in your browser, you can process large CSV files fast without bandwidth bottlenecks.
