Did you export the Google Vault data and are now facing the problem with the MBOX files? Here is the best workaround to convert Google Vault Chat MBOX files to PDF format. At the time of converting files into PDF, it becomes accessible Worldwide.

Google Vault allows exporting chat conversations as a file (e.g., MBOX), which is optimized to save the chat logs in the email format and keep the data saved. This is a good format to archive the chat logs, but not convenient to open or share without the appropriate program. This could have made it difficult for the user to use the chat conversation for legal and organizational purposes.

The translation of Google Vault chat files to PDF addresses the shortcoming by transforming the data into a universally accessible and readable document format.

What are Google Vault Chat Files?

Google Vault is the archiving and eDiscovery component of Google Workspace. It is mainly used by organizations to search and export Emails, chats, and files stored in Drive. When you export Google Chat data from Google Vault, you get it in MBOX format. It is a mailbox format that stores many messages in a single text file.

Use an email client to access MBOX documents. MBOX files are a broadly accepted email archive format, but there are some issues that users face while using them. You cannot open the file by double-clicking or print it:

This is the reason why converting Google Vault Chat files to PDF is very important to them in order to have a legal team, IT Admin, etc. So, let’s see why we convert to PDF and not other formats.

Google Vault vs Google Takeout

  • You have a Google Vault Export if an IT admin or legal team pulled the data from the Vault console, not the personal Google account. And the zip file is unzipped to one or more *.mbox files.
  • You have a Google Takeout export if you have requested the data yourself from takeout.google.com, and the download contains *.json files.

If the files you have are in *.json, then the guide is not what you need – navigate to Google Chat JSON to PDF instead. If you have *.mbox files, then read the rest of the article.

Why Convert to PDF for Google Vault Exports?

PDF format is the most preferred file format for document archiving for several important reasons.

  • Universal readability: Open the PDF files on any device, OS, or browser without the requirement of any software.
  • Print-ready: We can print the PDF files as they are. It is critical for the court’s legal purpose.
  • Tamper-Free: We can make the PDF files digitally locked, making them legally reliable as evidence.
  • Long-term Archiving: PDF files follow an ISO standard designed for long-term document preservation. It can embed metadata like author, date, and document properties.
