MBOX to CSV review
A Mac utility for local MBOX conversion, with a free tier for files under 50 MB.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MBOX to CSV is a macOS desktop utility for turning email archives into structured files. It is aimed at Mac users who need to work with MBOX data from sources such as Gmail Takeout, Apple Mail, Mozilla Thunderbird, or Fastmail. Solo users and small teams may find its focused scope a good fit, particularly when they need to extract email content or attachments for analysis, migration, or review.
Its conversion options go beyond choosing an output format: it can export to CSV, Excel, JSON, XML, or plain text, normalize dates, decode MIME and Base64 content, strip HTML, and remove duplicate lines. It also extracts attachments to a separate folder and can split large outputs into chunks. Multiple MBOX files can be imported. Processing takes place locally on the Mac, which suits workflows that call for desktop conversion rather than cloud processing. These tools make it more specialized than a general-purpose file converter, with particular value for email archives.
The free tier converts MBOX files under 50 MB; the Full Version unlocks conversion of larger files. That gives prospective users a way to assess the small-file workflow before deciding whether the full version fits their needs. Choose MBOX to CSV if you work on macOS and need batch conversion or cleanup options for MBOX archives. It is a less suitable choice for Windows users or anyone seeking cloud conversion. Support is offered by email, and the product does not include AI features.
