About this conversion
Mailing-list archives and server backups almost always arrive as .mbox.gz. Decompression happens in the browser as the file is read, so the extra round trip through an unpacking tool disappears.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
You are not locked into CSV
The file is parsed once and stays open, so the format is picked at the end rather than the beginning: the same .gz can leave here as XLSX, ZIP, EML, MBOX, PDF, HTML, TXT or JSON. Before that you can search it by subject or address, filter by year, sender and attachment type, mark the duplicates and look through the archive overview.
Questions
- Does .tgz from Google Takeout work too?
- Yes. Takeout hands out .tgz, and the tar inside it is read as well.
