About JSON to Excel Conversion

JSON (JavaScript Object Notation) is a popular data format for APIs and web applications. Converting JSON to Excel - or JSON to XLSX - makes it easier to analyze and share data with colleagues who prefer working with spreadsheets. This is also the fastest way to turn an API response into a JSON to spreadsheet export.

Our converter handles arrays of objects, converting each object to a row in Excel. Object keys become column headers. Nested objects are automatically flattened using dot notation (e.g., "address.city").

JSON Structures You Can Convert

Array of objects - the most common API shape. Each object is a row:

[
  { "name": "John", "email": "john@example.com" },
  { "name": "Jane", "email": "jane@example.com" }
]

Nested objects - flattened with dot notation into separate columns (address.city, address.zip):

[
  { "name": "John", "address": { "city": "NYC", "zip": "10001" } }
]

Arrays inside an object - your choice: expand lists of values into a comma-separated cell and lists of objects into indexed columns (items.0.name, items.1.name), or keep them as JSON text in one cell so nothing is dropped from the workbook.
