Transform Spreadsheets to Code

CSVs (Comma Separated Values) are the universal language of spreadsheets, but web applications speak JSON (JavaScript Object Notation). This converter bridges the gap, allowing you to easily move data from Excel, Google Sheets, or legacy databases into your modern web application.

Smart Parsing

Unlike simple string splitters, our tool handles complex CSV edge cases. It correctly respects quoted fields that contain delimiters (like "Doe, John") and automatically detects boolean values and numbers, so you don't have to manually clean your JSON output later.

Array of Objects vs Array of Arrays

By default, we assume the first row of your CSV contains headers (like "Name", "ID"). This produces an Array of Objects, where each row is a key-value pair. If your data has no headers, simply toggle the switch to generate an Array of Arrays, keeping the raw structure intact.
