Fun Fact About This Tool
Base64 encoding increases data size by roughly 33 percent, which means converting it back to CSV not only makes it readable again but also restores it to a smaller and more efficient format.
Historical Context of This Tool
Base64 encoding was originally developed as a way to safely transmit binary data over systems that only supported plain text, such as early email protocols. CSV files, on the other hand, have been a standard data exchange format for decades. This tool bridges the gap between those two technologies by reversing Base64 encoding and returning structured tabular data to its original form.
