Bridge the Gap Between Excel and Code
Business data lives in Excel. Application data lives in JSON. Getting data from one world to the other shouldn't require a developer or complex scripts.
Our converter handles Excel files directly—XLSX, XLS, and CSV. Upload your spreadsheet and get clean, properly structured JSON. Headers become keys, rows become objects.
Perfect for developers getting data from business teams, analysts preparing data for web dashboards, or anyone who needs to turn spreadsheet data into code-friendly format.
