What This Tool Delivers

Powered by the PapaParse library, this CSV to JSON converter transforms tabular data from spreadsheets and CSV files into structured JSON format with customizable options. Choose your delimiter (comma, semicolon, tab, or pipe), handle quoted fields, and convert data with or without headers. The tool automatically detects data types, converting numbers, booleans, and null values correctly.

Use it to transform spreadsheet exports for web APIs, import data into databases and applications, or enable complex data manipulation with JavaScript. The converter supports two output formats: array format for processing lists of records, and object format for data analysis and visualization.

CSV Conversion Best Practices

Delimiter Selection: Choose the correct delimiter for your CSV file. Common delimiters include commas (standard), semicolons (European format), tabs, and pipes. Powered by PapaParse, the tool handles quoted fields containing delimiter characters, escaped quotes, and complex CSV edge cases correctly.

Header Handling: Enable "First row is headers" if your CSV has column names. This creates meaningful JSON keys instead of generic column numbers. Headers are automatically trimmed and used as object keys.

Output Format: Use array format for processing lists of records (each row becomes an object). Use object format when you need column-based data structures for analysis or visualization.

Data Types: The converter automatically detects and converts numbers, booleans (true/false), and null values. Ensure your CSV data is properly formatted for accurate type detection.
