All processing happens in your browser. No data is sent to any server.
Decode a Base64-encoded CSV blob back into the original tabular text, ready for spreadsheets and ETL tools.
Recovering CSV fixtures stored in tokens, pulling data out of opaque API responses, or importing config tables stashed in Base64.
For file payloads, use Image to Base64 or recover an inline asset with Base64 to Image.
Does the tool detect the delimiter?
No. The decoder returns the bytes as-is; downstream tools handle the delimiter.
