What This Tool Does
This tool converts a JSON array of objects into a real, downloadable .xlsx spreadsheet. Paste or upload JSON, review the generated table in a live preview, and download an actual Excel file with proper column headers, ready to open in Excel, Google Sheets, or any spreadsheet app.
How to Convert JSON to Excel
Paste a JSON array of objects into the input, or upload a .json file. The preview table updates as you type, showing every column and how many rows and columns were found. Once the JSON is valid, click Download .xlsx to save a real spreadsheet file, no server round-trip involved.
How Columns and Missing Keys Are Handled
Spreadsheet columns are built from every key that appears anywhere in the array, in the order each key is first seen, not just the keys on the first object. If a later object is missing a key that earlier ones have, its cell is simply left blank in the spreadsheet rather than shifting other columns out of alignment or causing an error.
Why Download a Real .xlsx Instead of CSV
Some online converters just rename a CSV file to .xlsx or wrap an HTML table, which can break formatting, column types, or fail to open correctly in Excel. This tool generates a genuine binary .xlsx file using a proper spreadsheet-writing library, so the columns, headers, and cell values open cleanly in Excel, Google Sheets, or any spreadsheet application.
