I need a formula that removes duplicate data. The unique identifier would be email addresses. I read the best way to do this is to add a checkbox column for duplicates but I can't figure out the formula to automatically check the box if the email address already exists in the sheet. Please help!
I opened a support ticket, but I can't close this pop-up no matter what I click or what browser I use and I'm wondering if anyone has any insight. I'm LOCKED OUT of my work because of some stupid UI refresh alert. ?

hi all - quick question for you: When combining a few different lists into one list - whether it's manually uploading them or just adding them to a campaign - does klaviyo automatically remove duplicates?
As long as the email addresses are the same for the existing brand ambassadors profiles in Klaviyo, then no duplicate profiles will be created. New profiles are created in a .CSV upload only when there is no existing email addresses that matches the profile. So if you have 10 email addresses of existing brand ambassadors in Klaviyo, and you ensure that they match what already exists, but have 2 new email addresses of net-new brand ambassadors added, only 2 new profiles will be created.
Microsoft Outlook provides a variety of handy tools that we use and love and even more features that we are unaware of. But regrettably, the option to dedupe the address book and combine duplicate contacts into one is not on board.
Luckily, we are not limited to using only the tools provided explicitly by Outlook. With a bit of ingenuity, you can figure out a way to solve any, or nearly any, challenge that comes your way. This tutorial will teach you how to check Outlook contacts for duplicates and merge them without using any third-party software.
Regardless of the reason, duplicate contacts can be a real hassle in Outlook, making it difficult to keep track of important information and leading to confusion and errors. Understanding the reasons for contact duplication can help you take steps to prevent it from happening in the future. Below, you will find a number of solutions to resolve any existing issues.
How to remove duplicate contacts in OutlookTo delete duplicate contacts one at a time, this is what you need to do:
In most cases Outlook is smart enough to prevent duplication when you are trying to create a contact that already exists. However, if you have a number of duplicates in your address book, you need to apply a special technique to clean up the mess. The detailed steps follow below.
For this example, we will use Outlook 365, given its popularity in recent times. However, the options are essentially the same in all modern versions of Outlook 2021 to 2013, so you should encounter no difficulties following along.
Tip. When you have multiple contact cards for the same person, their details can be scattered across these duplicates, such as a business phone number on one card and a private phone number on another. In such cases, the Merge Duplicates tool can be very useful. This Excel add-in can easily merge all information from duplicate rows into a single row.
To get a better understanding of how this works, take a look at the original .csv file, which shows how the data is typically spread across multiple rows:By using the Merge Duplicates add-in, you can have all the details combined into a single, unified row:If you are interested to try this tool on your own data, you can download a fully-functional trial version here.
- Import contacts from CSV file to main Contacts folder.Start the Import/Export wizard again as described in the previous step and select the following options:
For more details, see How to import contacts to Outlook from CSV file.
- Merge deduped contacts with the original ones.Finally, you need to merge the deduplicated contacts that you've imported to your main Contacts folder with the original contacts that are currently in the Merge dupes folder, so that no contact details will get lost.
When done, click the Export button to complete the export process.
- Finally, import the merged contacts back into Outlook. To get rid of duplicate contacts, remember to select the Do not import duplicate items option.
Starting from version 2013, Outlook has an inbuilt feature that links all the contacts of a person and displays the combined information from all the linked contacts in a single contact card. The source of the data is also listed, making it easy to keep track of the information. Outlook usually does a decent job of matching contacts, but sometimes it messes up and links the wrong ones or doesn't link them at all. Fortunately, you can easily correct these links for individual contacts. Here's how:
Though the Link Contacts feature is not the ideal solution for cleaning up a large address book that is cluttered with duplicates, it can be a useful tool for quickly merging a few identical contacts into one.
How to prevent duplicate contacts in your OutlookNow that you've successfully eliminated duplicate contacts in your Outlook, it's worth taking a few extra minutes to learn how to maintain a clean address book going forward. Fortunately, this can be achieved easily by enabling Outlook's automatic duplicate contact detector. Here are the steps to do so:
Congratulations! You've successfully enabled the automatic duplicate contact detector in Outlook. From now on, every time you add a new contact with a similar name or identical email address, Outlook will suggest merging contacts to prevent the creation of duplicates. This simple step will help you keep your contact list clean and organized in the future.
That's how to get rid of duplicate contacts in Outlook. Remember to periodically review and update your contacts as needed to ensure that your list stays organized and up-to-date. Thank you for reading, and happy emailing!
This didn't work at all for me. It just copied the duplicates right back into the Contacts folder without any update dialog asking if I wanted to merge them. And yes, I did have the "check for duplicates" on.
The outlook solution worked for me...after I spend 3 hours figuring out why the Duplicate Contact Detected Wizard didn't show up! I finally figured out that there is a Outlook 2016 setting in "Options - People"-- check the "Check for duplicates when saving new contacts" box!
A common problem I have always had with importing/exporting CSV files: names in foreign languages that use diacritical marks (Garca, lvarez, Ral, Buuelos, etc.) often do not translate into the new version. Worse than being simply eliminated, however, they show up as the WRONG diacritical marks. For example, "Jos Lus vila" recently came out as "Jos Lus vila," which is effectively useless. Sometimes it works, but often it does not. Is there any solution for this?
Greg:
This is a known problem with Excel and as such has a number of different solutions depending on which version of Excel you are using.
The easiest answer is to suggest you do a search on Excel and UTF-8 characters and see the various solutions.
I have a number of contacts in which I will have pasted small image files in the Notes field. This would be such things as a business card scan, or some important notes gotten from a web site. Will these images survive your procedure for elimination of duplicates? If not, do you have a suggestion as to how I can preserve them with the appropriate contact?
How would I now best go about testing to see which contacts are still active? With over 10 years of collecting contact information I have to believe some of these are no longer valid. Do you have a recommendation for how to do that efficiently?
Hi Svetlana,
Does your guide work for Outlook in MS365? When I try to follow the steps, Ctrl A does not highlight the files to be moved. So I highlighted them manually and then the "Merge Dupes" folder does not appear when going to the "Move" steps. Any idea what's happening here?
Thanks.
