What Is This Tool?
The CSV to JSON Converter turns rows of CSV data with a header line into a JSON array of objects.
What Can You Do With It?
Convert spreadsheet exports for web apps. Prepare test data for APIs. Check CSV structure.
How Does It Work?
The PapaParse library reads the CSV, uses the first row as keys and turns each following row into an object. Empty lines are skipped and parsing errors are shown.
Key Benefits
Handles quoted values and commas inside quotes. Clear error messages.
Limitations and Important Notes
All values are output as text strings, including numbers. A header row is required.
Privacy and Security
This tool runs entirely in your web browser. Your input and results are processed on your device and are not uploaded to Usekit servers.
Real-World Example
Input: name,age Ava,30 Leo,25 Output: [{"name":"Ava","age":"30"},{"name":"Leo","age":"25"}] (formatted).
Frequently Asked Questions
Why are numbers in quotes?
Values are kept as text so nothing is changed by mistake, such as ZIP codes with leading zeros.
Can I use semicolons?
PapaParse tries to detect the delimiter automatically.
Is my file uploaded?
No, conversion happens in your browser.
