Parse CSV files into clean JSON objects with RFC 4180 compliance for quoted fields, escaped characters, and embedded commas.

## What is CSV to JSON converter?

Turn spreadsheet exports and data tables into formatted JSON arrays. Automatically infers data types (casting numeric strings to numbers and "true/false" to booleans) with customizable delimiter settings.

## How to use CSV to JSON converter

1. **Add your file or input** — Choose a supported file, drag it onto the upload area, or type/paste the data this tool works with.
2. **Adjust the options** — Pick the output format, quality, size or other settings the tool offers. Defaults work well for most files.
3. **Process and download** — Run the tool and save the result. Processing happens in your browser, so nothing is uploaded to a server.

## Frequently asked questions

### Does the converter automatically parse numbers and booleans?

Yes. You can toggle auto-type inference to convert values like "42" into numeric 42 and "true" into boolean true, or preserve everything as raw strings.

### Are custom delimiters like semicolons (;) or tabs (TSV) supported?

Yes. You can specify standard commas, semicolons (common in European Excel exports), tabs, or pipe (|) delimiters.

### How does it handle quotation marks and commas within cells?

It strictly adheres to RFC 4180 CSV standards, parsing escaped quotes ("") and commas enclosed within quotation marks correctly.
