About CSV/JSON Conversion

100% Client-Side & Private: All conversions happen locally in your browser. Your data never leaves your device.

What is CSV? Comma-Separated Values - a simple text format for tabular data where each line represents a row and values are separated by delimiters.

What is JSON? JavaScript Object Notation - a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate.

CSV to JSON: Converts CSV data into structured JSON objects. The first row can be used as property names (headers) for each object.

JSON to CSV: Converts JSON arrays into CSV format. Nested objects can be flattened using dot notation (e.g., user.name).

Excel Support: Upload .xls or .xlsx files directly - they will be automatically converted to CSV format first.

Delimiters: Choose from comma, semicolon, tab, or pipe characters to match your CSV format. Auto-detect will try to identify the delimiter automatically.

Use Cases: Data migration, API integration, spreadsheet processing, database imports/exports, data transformation, file format conversion.
