First is the overall complexity of an Excel file and its proprietary nature. Unlike Thunderbird, Excel is not open source. Moreover, Microsoft has designed this spreadsheet tool to be more than just tabular storage. This helps out in other situations, like data analysis, but only poses a hurdle in our case. The highly complex structure allows another drawback. It’s quite easy to hide malicious macros inside innocent-looking Excel workbooks. So to prevent any trojan horse attempt via XLSX files, many apps outright forbid the addition of these files. Thunderbird is just another app that follows this industry standard.
So if you wish to update your existing Thunderbird contact list. Or even create a brand new one, where an Excel file is the primary source. You have two methods for achieving this. One is where you export the Excel data into CSV and then bring that CSV into Thunderbird. The second and better option is using vCard as the intermediary between Excel and Thunderbird address books.

Why Go for vCard over CSV as the Contact Delivery Format in Thunderbird

Although Excel can directly export an XLSX document in CSV format, the issue lies in the encoding you receive. Depending on the Excel version, you might get CSV files that are not acceptable as the standard encoding. So importing such a CSV file creates a major risk of data loss or mismatch.
Whereas vCard has 3 distinct versions: 2.1, 3.0, and 4.0, each of which is better than the last. This, combined with no encoding issues, gives the vCard format an edge over its contemporary.
CSV is primarily a text file with a more general purpose usage. This means that even though it can be used to store contacts, it was not designed for this task. On the other hand, VCF is a purpose-built solution for the sole task of keeping contact files. Thus, it is easier for programs like Thunderbird to extract information and fill an Address book with vCard data.

Frequently Asked Questions

Q. I want to upload an email contact list from Excel in the Thunderbird address book how to do that?

  • Open Thunderbird and go to Address Book
  • Press the New List button.

Q. Is there a chance of data loss if I try to add an Excel file to Thunderbird on my own via CSV?
Ans. When you use CSV format as the bridge then you automatically increase the chances of data loss. As during CSV conversion Excel might automatically group multiple phone numbers into a single field. This requires additional manual intervention and thus more chances where oversight occurs resulting in a faulty import job.

Q. Do I need to make any changes in my Excel sheet before adding it to the utility?
Ans. If your Excel file already has an appropriate heading for each column then no other change is required. The tool can load the data from even password-protected files and change them into VCF format.
