Converting Base64 encoded data back to DOCX documents allows you to retrieve Microsoft Word files that were previously encoded for transmission or storage. DOCX files are actually ZIP archives containing XML files and other resources that make up the document.
The tool validates the DOCX format by checking for both the ZIP signature and DOCX-specific XML structure. This ensures you're working with valid Word documents before downloading them.
