JSON to CSV: open API data in Excel or Google Sheets
JSON is the standard exchange format of modern APIs, but it can’t be used directly in a spreadsheet. Converting to CSV turns a JSON array of objects into a file importable into Excel, Google Sheets, Numbers, or any analysis tool (Power BI, Tableau). A quick check can prevent problems later.
Each object becomes a row, each key becomes a column
A JSON like [{"name":"Marie","age":30},{"name":"Jean","age":25}] becomes a CSV with two columns (name, age) and two data rows. Keys of the first object serve as headers. Missing values in some objects produce empty cells. Conversion is available on the free plan within its daily usage quota.
Nested objects are flattened or serialized
A JSON with nested objects (address: {street, city}) is either flattened into separate columns (address. street, address. city) or serialized as JSON into a cell, depending on options. Nested arrays are serialized to stay readable. Current quotas and higher plans are shown on the Pricing page.
