What is a JSON file?
JSON is the data format of the modern web: nested keys and values that every programming language parses natively. APIs speak it, apps are configured with it, and it stays readable, diffable text throughout.
What is a XLSX file?
XLSX is Excel's native format: multiple sheets, formulas, charts, formatting and proper data types in one file. Google Sheets, LibreOffice and Numbers all open it too.
Why convert JSON to XLSX?
JSON's nested structure doesn't drop into spreadsheets or data tools row-by-row without flattening it first. XLSX opens straight into Excel or Google Sheets with data types, multiple sheets and formatting intact.
