Challenges to Convert Thunderbird Files to CSV
——————————-
| Problem | Explanation | Why |
| No Direct CSV Export Option | Thunderbird lacks a built-in option to export messages to CSV. | Users must first export messages as EML or in an MBOX format and then convert to CSV later. |
| Loss of Email Formatting | Any email formatting, inline images, and HTML content are not preserved in CSV.
|
CSV excels as a text-only format, so all formatting, visual elements, or rich-text elements are lost. |
| Incomplete Data Export | Some fields, such as Cc, Bcc, or attachment detail, may not be accurately exported. | This may require manual workarounds or add-ons to retrieve some elements. |
| Performance Issues with Large Mailboxes | Exporting a large number of emails can cause Thunderbird to become slow or crash.
|
It is not purposefully developed for bulk email export options; therefore, it interferes with rendering slow functionality or export workflow. |
| Add-on Compatibility Issues | Add-ons used to perform the export may not work with the most current version of Thunderbird.
|
New versions of Thunderbird come with updates frequently, which may interfere with other third-party extensions. |
How to Export Thunderbird to CSV Using Manual Method?
——————————-
Here we’ll discuss the manual method to see how to export our email data from Thunderbird to a CSV file. In this method, we are going to use an Add-on that will export user emails from Thunderbird to CSV format.
The detailed steps are given below:
- Initially, open Thunderbird on your system.
- Then, click on the Menu >> Add-ons and Themes >> search ImportExportTools NG, then click Add to Thunderbird and install.
- Further, in Thunderbird, select the email folder you want to export and right-click on that folder.
- After that, choose ImportExportTools NG >> Export folder >> As CSV file.
- Finally, from the window, choose the saving location and click Save.

- Large mailboxes take too much time to process.
- Some emails or fields may be skipped or duplicated during export.
- Risk of missing important fields during conversion.
- Special characters or non-English text may appear as garbled symbols in the CSV.
