Overview

What Is MBOX to CSV Conversion?

MBOX to CSV converts an MBOX mailbox file (used by Thunderbird, Apple Mail, and Gmail Takeout) into a CSV (comma-separated values) spreadsheet. Each email becomes one row; columns include From, To, Subject, Date, and a short body preview. CSV is universally supported by Excel, Google Sheets, and data analysis tools.

Converting MBOX to CSV is useful when you need to analyze email metadata without opening each message: filter by sender or date, build reports, run formulas, or prepare data for CRM or migration. Our tool processes on your device and does not upload your file.

Exporting to a spreadsheet makes it easy to see patterns, count messages by sender, sort by date, and share summary data. The result is a single .csv file you can open in any spreadsheet application. For full body content or developer use, consider MBOX to TXT, HTML, or JSON from the main MBOX converter.
