CSV to JSON Converter

Simply paste your CSV data into our converter, choose your formatting options, and click "Convert to JSON". Our tool processes the conversion instantly in your browser - no registration or payment required. You can then download the JSON file or copy the output directly.

Our converter supports all common CSV delimiters including commas (,), semicolons (;), tabs, and pipes (|). You can select the appropriate delimiter from the options, and our parser will automatically handle quoted fields and escape characters properly.

Yes! Our converter automatically detects and converts data types including numbers, booleans (true/false), null values, and dates. You can enable or disable this feature in the conversion options. When disabled, all values are treated as strings.

We offer three JSON formats: "Array of Objects" (most common - each row becomes an object), "Object with Arrays" (each column becomes an array), and "Grouped by Column" (data grouped by column values). Choose the format that best fits your application needs.

The converter can automatically detect if your CSV has headers in the first row and use them as JSON object keys. If no headers are present, it will generate generic column names like "column1", "column2", etc. You can toggle this setting in the conversion options.

Absolutely! All conversion happens locally in your browser - no data is sent to our servers. Your CSV and JSON data never leaves your device, ensuring maximum privacy and security for sensitive business or personal information.

While our tool specifically converts CSV format, you can easily export your Excel file as CSV first (File > Save As > CSV in Excel), then use our converter. This two-step process gives you full control over the data and ensures compatibility.

Our browser-based converter can handle CSV files up to 100MB, depending on your device's memory and processing power. For larger files, we recommend breaking them into smaller chunks or using the tool on a device with more memory.

Yes! You can copy data directly from Google Sheets and paste it into our converter, or download your Google Sheets as CSV format first. Our tool handles both approaches seamlessly and maintains data integrity throughout the conversion process.

Currently, our tool processes one CSV file at a time to ensure optimal performance and accuracy. For multiple files, you can merge them into a single CSV first or convert them individually. We recommend this approach for better control over the conversion process.

Yes, our CSV to JSON converter is completely free to use with no registration required. You can convert unlimited CSV data, download JSON files, and access all features without any charges. The tool is designed to be accessible to developers and data professionals worldwide.
