What is CSV to JSON Converter?
A CSV to JSON converter transforms comma-separated data into structured JSON format. This is essential when migrating data between systems, preparing API payloads, or converting spreadsheet exports for use in web applications.
How to Use
- Paste your CSV data or upload a CSV file
- Verify the detected delimiter (comma, semicolon, or tab)
- Preview the parsed data in a table view
- Copy or download the resulting JSON array of objects
Frequently Asked Questions
- Does the first row need to be headers?
- Yes, the first row is used as property names in the resulting JSON objects. Without headers, you'll get generic indexed keys.
- How are numbers and booleans handled?
- Most converters auto-detect numeric strings and convert them to number types. Values like 'true' and 'false' can optionally be converted to booleans.
- What if my CSV uses semicolons instead of commas?
- Select or auto-detect the delimiter. European CSV files often use semicolons because commas are used as decimal separators.
