JSON to Excel
Convert a JSON array into an Excel .xlsx workbook. An array of objects uses the keys as column headers. A two-dimensional array is written row by row.
The download is one worksheet named Sheet1. .xlsx is the Office Open XML workbook defined by ECMA-376. Excel, Google Sheets, and LibreOffice open it. Microsoft lists it among the file formats Excel supports.
The input must be valid JSON as defined by RFC 8259. Object keys from the first item become the header row.
Cells are stored as text, so a code like 001 is not shortened into a number. Formula-like text such as =1+1 is stored as text and is not calculated on export.
