Why Convert CSV to JSON?
JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. Converting CSV to JSON transforms tabular data into a structured format that's easier to work with in programming languages and web services.
Our converter automatically detects data types, handles quoted fields, and supports various delimiters to ensure accurate conversion from CSV to JSON format.

Frequently Asked Questions
What if my CSV has no headers?
Uncheck "First row is headers" and the converter will create a JSON array of arrays instead of objects with named properties.
How are data types handled?
The converter automatically detects numbers and booleans. Numbers are converted to numeric types, "true"/"false" become booleans, and everything else remains as strings.
Can I handle CSV files with quotes and commas?
Yes, the converter handles quoted fields properly. Fields containing commas, quotes, or line breaks should be enclosed in double quotes in the CSV.
What's the maximum file size supported?
The converter processes data in your browser, so it's limited by available memory. For very large files (>10MB), consider splitting them into smaller chunks.
