One row per email. Including the ones without files.
The CSV contains the message reference, sender name and address, To, Cc and Bcc when present, full subject, original date header, UTC date, source-message size, attachment count and attachment names. It follows the order of your MBOX file.
| Subject | From address | Attachment count |
|---|---|---|
| text: September receipt | text: maya@example.test | 1 |
| text: Meeting notes | text: leo@example.test | 0 |
What is included—and what is separate?
This is an email-metadata export: message bodies and attachment contents are not inside the CSV. The current search and filters define the emails exported. Selecting attachment checkboxes changes your ZIP selection, not the email list.
To download the actual files, use the Download button beside an attachment or export selected attachments together. The ZIP includes its own attachment index, with one row per exported attachment.
Opening the CSV in Excel or Google Sheets
Open emails.csv in Excel, or use File → Import in Google Sheets. The file uses UTF-8 and comma-separated columns. If your spreadsheet shows everything in one column, use its import option and choose comma as the separator. Multiple recipients and attachment names appear on separate lines within a cell.
Text cells begin with text: so email content is treated as text instead of a spreadsheet formula. Counts and sizes remain numbers. The prefix is intentional; removing it from untrusted content can expose formulas. Original and UTC dates are separate, and an unknown date remains empty after the text prefix.
Private processing, clear limits
Your archive is read on your device. CSV exports are free and limited to 64 MiB per download. If a list exceeds that size, narrow it with sender, date or search filters. The reader supports one conventional MBOX file at a time, up to 100,000 messages and 64 MiB per message; other processing limits apply.
Starting from Gmail? Follow the Google Takeout guide to obtain your MBOX file. To read the archive in a desktop mail app, see importing MBOX into Thunderbird.
