Convert JSON to CSV for Excel / Sheets

The JSON to CSV Converter is a professional utility for "flattening" hierarchical JSON data into a tabular format. This is the gold standard for data analysts who need to import API responses or database blobs into Microsoft Excel, Google Sheets, or business intelligence tools.

Expert Data Flattening

Dot Notation

Nested objects are automatically flattened using dot notation (e.g., user.address.city) to preserve structure in a flat CSV file.

Array Handling

JSON arrays are intelligently processed into individual rows or joined strings to ensure your spreadsheet remains clean.

Why Privacy is Critical

Data transformation often involves sensitive user lists or financial records. Most online converters upload your data to a remote server. At Kodivio, your JSON never leaves your browser.

All processing is 100% Client-Side. Your data is your own.

Can I export to Excel directly?

Does it support custom delimiters?

Our tool produces standard comma-separated values, but you can use our JSON to TSV tool if you need tab separation.
