FAQ
Does the converter detect data types automatically?
Yes! Numeric values are converted to numbers, "true"/"false" become booleans, and everything else remains as strings. This ensures your JSON is ready for immediate use in JavaScript applications without additional parsing.
Why convert CSV to JSON?
Converting CSV to JSON is useful when you need to integrate data into a system that only accepts JSON format. Comma-Separated Values - Simple tabular format can be transformed into JSON (JavaScript Object Notation - Lightweight data interchange format) for better compatibility.
Is my data secure during conversion?
Absolutely. Our converter works 100% client-side (in your browser). Your CSV data is never sent to an external server. Processing is instant and completely private.
What is the maximum CSV file size supported?
Since processing happens in your browser, the limit depends on available memory. Generally, files up to 10 MB are processed without issues. For larger files, we recommend splitting them.
How does CSV to JSON conversion work?
Our tool parses your CSV file, analyzes its data structure, then generates the equivalent in JSON format. Arrays, objects, and primitive values are intelligently mapped to JSON syntax.
Can I convert JSON to CSV?
Yes! We support bidirectional conversion. Use our JSON to CSV converter for the reverse operation.
