About JSON to Excel Converter
Sharing JSON data with non-technical stakeholders often means converting it to a familiar spreadsheet format. Manually copying values into Excel is tedious for large datasets. This JSON to Excel converter creates XLSX files directly in your browser with proper column headers and row data.
How it works
Paste a JSON array into the Input area. Each object in the array becomes a row in the spreadsheet. Set the Sheet Name if you want something other than the default. Click Download Excel and the file is generated instantly using the XLSX library.
Nested objects are flattened with dot notation for column names. Arrays within objects are converted to comma-separated strings. The Output Status panel confirms how many rows and columns were created in your spreadsheet.
When you'd use this
Data analysts receiving JSON exports from APIs need to analyze the data in Excel. Product managers want to review feature flags or configuration data in a familiar spreadsheet view. This tool bridges the gap between developer formats and business users.
Very wide JSON objects with many unique keys create spreadsheets with many columns. Deeply nested structures may produce long column names. For complex data, consider flattening your JSON structure before conversion.
Questions
Does it handle nested objects?
Yes. Nested properties are flattened using dot notation like address.city for column headers.
What about arrays inside objects?
Array values are joined into comma-separated strings within a single cell.
Can I convert a single JSON object?
Yes. Single objects are wrapped in an array and converted as a one-row spreadsheet.
Is the Excel file generated online?
No. The XLSX file is created entirely in your browser using the xlsx library. No data is uploaded.
What Excel version is supported?
The XLSX format works with Excel 2007 and later, plus compatible tools like Google Sheets and LibreOffice.
