How to Convert JSON to Excel So People Can Actually Review It

Start with the shape of the JSON

The easiest JSON to convert is an array of similar objects: one object per record, with consistent keys. Product lists, user exports, event logs, and order records often work this way.

Deeply nested JSON is harder. A customer record with addresses, orders, tags, and preferences may need flattening before it becomes a readable spreadsheet.

Watch nested fields

Nested objects may become columns with longer names, such as customer.email or billing.address.city. Arrays may be joined into one cell or expanded into multiple rows depending on the converter.

• - Flat records usually convert cleanly.
• - Nested objects need readable column names.
• - Arrays may need a separate sheet or manual cleanup.
• - Missing keys create blank cells.
• - Mixed data types should be checked before import.

Check IDs, dates, and booleans

Excel may treat values differently from JSON. Long IDs can turn into scientific notation, dates can be reformatted, and true or false values may become text. Check those fields before sending the spreadsheet to another system.

Use Excel for review, not as the only source of truth

Once JSON becomes a spreadsheet, the structure is easier for humans but less precise for systems. Keep the original JSON export, especially if you may need to import the data back into an app.
