What is an Excel to JSON/CSV Converter?
This tool allows you to transform spreadsheet data (Excel files) into developer-friendly formats like JSON (JavaScript Object Notation) and CSV (Comma Separated Values). It bridges the gap between business data (spreadsheets) and application data (code).
Developers often receive data in Excel files from clients or non-technical team members. Importing this data into a database or application usually requires converting it first. This tool automates that process entirely in your browser.
It parses `.xlsx` and `.xls` files, reads the headers from the first row, and maps every subsequent row into a clean JSON object or a CSV line. Since it runs locally, it's perfect for sensitive data that you don't want to upload to a third-party server.
1How to Use
- Upload File: Click the upload box or drag-and-drop your `.xlsx` or `.xls` file.
- Preview Data: The tool displays the first 5 rows in a table so you can verify the headers and values.
- Check Count: Confirm the total number of rows detected matches your expectation.
- Download JSON: Click to get a structured `.json` file representing your data as an array of objects.
- Download CSV: Click to get a raw `.csv` text file suitable for database imports.
