API output does not open in Excel on its own. Filemorph converts a JSON array into a real spreadsheet on your iPhone, ready to sort, filter and chart.

A JSON export from an API, an app or a database dump holds the same kind of data a spreadsheet does, just in a format Excel cannot open directly. Filemorph reads the JSON array and writes it into an XLSX workbook, one row per object and one column per field.
Filemorph builds the column headers from every field name found across the array, so objects with slightly different shapes still line up correctly, and writes numeric values as real spreadsheet numbers rather than a wall of quoted strings. The result opens straight into Excel, Numbers or Google Sheets, ready to work with.
In the app: Convert → JSON → Excel.
Excel is where most non-developers actually look at data — sorting, filtering, building a quick chart — none of which JSON supports on its own. Converting JSON to a workbook turns raw API or export data into something anyone on the team can open and use.
Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This operation is part of Filemorph Pro ($29.99/year, 7-day free trial on monthly and annual plans).
Yes. Every field name found across the array becomes a column, and objects missing a given field get an empty cell there.
Yes. Numeric values in the JSON are written as real numbers in the spreadsheet, so sums and sorting work correctly.
Yes. Filemorph's Excel to JSON operation exports a spreadsheet's rows as a JSON array.
On-device, no upload. Plus 300+ more file operations.
