MBOX to CSV — convert a mail archive without uploading it
Turn an mbox archive into a CSV table right in your browser: date, sender, subject, size and the list of attachments. The file is never sent anywhere.
About this conversion
Mbox is the format Thunderbird, Apple Mail and Google Takeout hand your mail back in: every message stacked into one long file. CSV opens in Excel, Google Sheets or Numbers, which makes this export the right one when you need to count, sort or pass a correspondence on as a report.
Just want to look inside it?
The same tool without converting anything: open a .mbox 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 .mbox can leave here as XLSX, ZIP, EML, 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
- What columns does the table have?
- Date, from, to, cc, subject, message size, number of attachments, their file names and the first lines of the text.
- Can I pick the messages first?
- Yes. Search and the filters (year, sender, attachment type) narrow the list, and the CSV contains exactly what you see on screen.
