User Query: I have one file containing the contact list. It was created in a spreadsheet and saved as a CSV. I want to import them into Outlook. Is there a way to import that CSV file into Outlook in the same format?
– By Derek Simmons (IT Employee, USA)
Introduction: Outlook is an email client by Microsoft. Till today, it remains a widely used tool for businesses to manage their contacts. Mostly, what users want is that they can import contacts from excel sheet to Microsoft Outlook without dealing with any kind of formatting errors.
You may think that it is easier to move the spreadsheet into Outlook because the data is already organized and ready. Whereas Outlook shows weird text and misread fields/duplicates when we import contacts to Outlook from Excel sheet. That’s why it’s good to use Aryson Excel to vCard Converter. It converts the spreadsheet into a clean and correctly mapped file that can be read by Outlook without errors.
Microsoft Outlook can never read an Excel workbook directly. That’s why many people search for a way to Import Contacts XLSX to Microsoft Outlook. Neither in Classic Outlook nor in redesigned Outlook, the import tool of Outlook only recognizes a small set of file types.
The file first has to be converted. Therefore, almost every process you will follow starts by “saving your spreadsheet as CSV” once your CSV file is ready. Outlook can easily read every row as one contact list and drop it directly into the default contacts folder. Here people get stuck; even those who are familiar with these things make mistakes.
For example, if you try to move larger files. They have more contact information, and directly importing those into Outlook can go wrong. Outlook adds them individually, like individual entries. It does not automatically organize them into separate groups or categories.
The actual problem lies in the new Outlook because it handles contacts very differently from the older one. Classic Outlook was straightforward; for example, the steps were
Giving users a clearer process, like
The newer version of Outlook didn’t contain these features. For the newer version of Outlook, importing a new CSV file means you have to follow these steps.
And this is significantly different compared to older versions, which is why till today people trying to import contacts to Outlook from Excel sheets get stuck. Once the import is completed, there may be some issues that occur.
The real challenge comes when you Import Contacts from Excel Sheet To Microsoft Outlook, and data quality becomes the issue. Either headers of different columns in a manually built spreadsheet or pulled from a CRM. Neither of them matches what Outlook expects. Due to this, the mismatch remains hidden until you group the contacts. General problems include:
Outlook has built-in mapping to catch some of these inconsistencies. But it’s slow, exposed to errors, and there’s no preview of what we are importing. Which is why Derek ran into this problem when trying to import his CSV file into Outlook cleanly.
That’s the gap a dedicated conversion tool fills. You may proceed to read through the manual methods discussed below. In case none of these methods work well for you or meet certain requirements, opt for the dedicated software discussed in the upcoming sections of the article.
So, here’s how you can transfer contacts from excel sheet to microsoft outlook account using one of these two methods:
The manual method is dependent entirely on Outlook’s built-in method. That’s why users prefer this method for shorter files, as it’s simple and doesn’t require installation of additional software. So, to transfer contacts from Excel sheet to Microsoft Outlook account, follow the below-given steps.
→ In some organizations, people still work on Classic Outlook. So, if working in Classic Outlook to import contacts to Outlook from Excel sheet, follow these steps:
→ If working in the newer Outlook or Outlook on the web
→ We can also import Contacts Excel to Microsoft Outlook manually, but Outlook Web has a max limit of 10 MB.
There are major drawbacks to manual methods. When you manually transfer contacts from Excel sheet to Microsoft Outlook account, which are
The Aryson Excel to vCard Converter tool totally removes the need for the manual method. The manual method needs Outlook for field matching, which is limited. This tool can handle the whole conversion easily without Outlook. It can directly read files and allows you to preview them before proceeding. Giving you a clean CSV file that Outlook can read without any errors.

However, following the above steps to import Contacts Excel to Microsoft Outlook, you will accomplish the required task, there is more offered by the software. Therefore, it is recommended to follow the Detailed Documentation of the Aryson Excel to vCard Converter to reduce the possibilities of data corruption. By the end of this article, irrespective of your expertise, you will be able to operate the software on your own.
So, in conclusion, importing a spreadsheet into Outlook is not a simple process. Either you depend on a manual method or a dedicated tool. The manual method can’t keep up when we need to convert a larger number of files. That’s why for larger files—much like Derek’s situation—a dedicated tool is a more reliable path. That provides features, such as mapping, cleaning, and formatting.
Ans. No, Outlook doesn’t support “.xlsx” directly. First, you need to save that sheet as a CSV file or convert it with a dedicated tool like Aryson Excel to vCard Converter, which can convert your file into CSV and other supported formats directly from the original Excel file without any kind of manual setup.
Ans. No, not directly, and that’s true. The software’s job is to turn your Excel file into a clean and correctly mapped file Outlook can import without errors. For building actual groups inside Outlook, it comes under different steps because the Contact List or Contact Group is an actual Outlook object, not something that a conversion tool can write into a different file.
Ans. Their purpose is the same, and that is to send one message to everyone in the set, but the actual difference is the name and process behind them. To create a contact group in Outlook, just select multiple existing contacts in the Select Members window and get added together. In the newer version of Outlook or Outlook Web, consider the same thing as a contact list.
Ans. This problem arises due to Outlook not being able to match the expected field names with the imported file’s column headers, etc. Usually, previewing files and mapping fields properly manually before conversion, which Aryson Excel to vCard Converter does support, catches this before the file even reaches Outlook.
Ans. Yes, this tool can do that using the Remove Duplicates option that checks the loaded data for repeated entries and filters them out. As the file conversion starts, they are also removed.
Ans. Yes, paste all addresses in the BCC field for a single email, but it’s a one-time send. It doesn’t import Excel contacts to Outlook as a single contact group.
Ans. No, working as an individual Excel-to-Outlook converter, it reads Excel and just gives CSV files directly and produces its output without relying on any other software. So neither Microsoft Excel nor Outlook needs to be installed on your system.
Ans. Yes, Aryson offers its users a free demo version of the tool that runs as a full conversion tool on the first 50 rows of the file. This is basically enough to confirm your mapping and review the output before purchasing the full version.
Ans. This could be due to some known issues such as file types and mismatched formats. There are several other issues, which are listed below
➡️Wrong file type: Outlook’s import tool doesn’t support Excel file format directly. So make sure to change the file format to CSV
➡️Column mismatch: Outlook needs a proper header row to map columns
➡️Corrupted files: Sometimes files are malformed or inadequate, like commas in a field, line breaks, etc
Ans. Yes, but not directly, as Outlook doesn’t support it. You have to convert that Excel file into CSV format, which is supported by Outlook. Then you can import your contacts into Outlook. For detailed steps, you can check the above section.
