XLSX conversion result

Your JSON data is transformed into spreadsheet rows and columns. Nested fields are flattened into readable column names, and the full result downloads as a modern .xlsx workbook.

When to use XLSX instead of XLS

XLSX is usually the better format for current spreadsheet work. Choose XLSX when you are using modern Excel, importing into Google Sheets, handling larger datasets, or sharing a workbook with teams that do not need old Excel 97-2003 compatibility.

FormatBest forUse when
XLSXModern Excel workflowsYou want the current Excel format for analysis, sharing, Google Sheets import, or larger structured data exports.
XLSLegacy compatibilityAn older tool, upload rule, or spreadsheet workflow specifically requires the older .xls format.

JSON arrays, nested objects, rows, and columns

Spreadsheet tools expect tabular data. This converter turns JSON arrays into rows, object keys into columns, and nested objects into flattened column names so the exported XLSX file is easier to filter, sort, and review.

Arrays become rows

Each object in a JSON array becomes a row in the spreadsheet.

Keys become columns

Fields such as name, email, or status are converted into spreadsheet columns.

Nested data is flattened

Nested objects become readable columns such as customer.address.city.

Browser-based conversion

The conversion runs in your browser. Your JSON is not uploaded to a remote server while the XLSX file is created.
