About the Excel to JSON Tool
Excel is where business data actually lives โ budgets, inventories, customer lists, product catalogues. Getting that data into an application usually means an intermediate CSV export, which loses sheet structure and introduces its own encoding headaches.
This tool reads .xlsx files directly using SheetJS, parsing the workbook in your browser and producing JSON from the sheet contents. No Excel installation is needed, no export step is required, and the file is never uploaded โ which matters when the spreadsheet contains commercial or personal data.
How to Use Excel to JSON
- Select your .xlsx or .xls file.
- Choose the sheet you want to convert if the workbook has several.
- Press Convert to parse the sheet into JSON.
- Copy or download the resulting output.
When to Use This Tool
- Importing a product catalogue from Excel into a web application
- Converting a budget or inventory sheet for use in a dashboard
- Turning spreadsheet data into API seed data
- Extracting structured data from a report workbook
- Building JSON fixtures directly from a business spreadsheet
Things Worth Knowing
- The first row is treated as the header and supplies the JSON keys.
- Formulas are read as their computed values, not as formula text.
- Cell formatting, colours, merged cells, and charts are not represented in JSON.

Frequently Asked Questions
Are Excel formulas converted?
Their calculated results are read, not the formula expressions. If a cell shows 42 from a SUM, the JSON contains 42.
Can I convert a workbook with multiple sheets?
Yes. Select which sheet to convert. Each sheet is a separate table and converts independently.
How are dates handled?
Excel stores dates as serial numbers internally. The parser converts recognised date cells into readable date strings, though unusual custom formats can occasionally need checking.
Is my spreadsheet uploaded anywhere?
No. SheetJS parses the file in your browser, so commercial and personal data stays entirely on your device.
