Convert DB.CRYPT7 to XLS

In order to work with the data inside some of the older versions of WhatsApp's CRYPT format (CRYPT5, CRYPT7, etc.), you will first need to utilize programs that convert these files to the original CRYPT format. To do that you will need to first convert CRYPT7 to CRYPT. The file can be found as msgstore.db.crypt7, but remember that only the CRYPT7 is the actual file extension.

Next you can use programs and websites like Whatsapp Extractor or WhatCrypt to export the chat backups from WhatsApp Messenger (.crypt files) and save them in an HTML file. This file, when opened using a web browser, will look exactly like your WhatsApp (CRYPT to HTML conversion).

Many word processors, including Microsoft Word, accept HTML files nowadays. You can open/import them to these programs and save them as documents (.doc/.docx). They will most likely appear similar to WhatsApp, as the HTML is heavily formatted. You might also try some of the HTML to XLS converters.
