Convert XLSX (Excel) to JSON

Convert XLSX to JSON for a database import, export comparison, or code that processes an Excel workbook. Sheet data is kept as separate structured tables.

JSON structure

The result always contains source information, conversion time, text pages, and tables. For a workbook without text pages, pages is an empty array and sheet data is in tables.

{
  "source": { "filename": "report.xlsx", "format": "xlsx", "pages": 0, "size_bytes": 18432 },
  "converted_at": "2026-09-17 10:30:00",
  "pages": [],
  "tables": [{ "page": 1, "header": ["Product", "Quantity"], "rows": [["Cable", "12"]] }]
}

• source contains the name, format, and size of the original workbook.
• pages is always present and is empty for a workbook without extracted text.
• tables holds sheet headers and rows; it is an empty array if there is no data.

Styling, column widths, charts, and formula formatting do not carry over: JSON holds cell data.

How to convert

1. Upload an XLSX workbook.
2. Select JSON as the target format.
3. Download the finished JSON and process its tables in your code.

For a single table in a text-based format, use the XLSX to CSV converter.
