Convert your CSV files into JSON format. Our free online tool makes it easy to transform your tabular data into structured JSON for use in web applications, APIs, and more.
Upload CSV file or paste CSV content:
Our CSV to JSON converter allows you to transform CSV (Comma-Separated Values) files into JSON (JavaScript Object Notation) format. Simply upload your CSV file, configure any parsing options if needed, and download the generated JSON file.
You can customize the delimiter (comma, semicolon, tab, etc.), specify whether your CSV has a header row, and choose how to handle quotes and special characters. These options help ensure accurate conversion of your specific CSV format.
Yes, our tool provides a preview of the converted JSON data before you download it. This allows you to verify that the conversion meets your expectations and make any necessary adjustments to the parsing options.
Yes, you can upload CSV files up to 10MB in size. For larger files, we recommend splitting them into smaller chunks or using a desktop application.
Most conversions are completed within seconds. The exact time depends on the file size, complexity of the CSV structure, and your device's processing power, since all processing happens directly in your browser.
Yes, we take data security seriously. This tool processes your files entirely in your browser - your CSV files are never uploaded to our servers. This means your data never leaves your device, ensuring complete privacy and security.
Converting CSV to JSON is useful for many purposes: preparing data for API consumption, importing data into JavaScript applications, creating configuration files, or transforming tabular data into a hierarchical format that's easier to work with in modern web development.
While this tool specifically converts from CSV to JSON, we also offer a JSON to CSV converter in our toolbox that allows you to convert in the opposite direction.
No, we don't store any of your files. Since the conversion happens entirely in your browser, your CSV data never reaches our servers. Once you close the browser tab or navigate away, all processed data is automatically cleared from your browser's memory.
