Remove Duplicates in Excel Tables using Data Explorer Add-in:

Standard

In this blog post, we’ll see how you can remove duplicated and clean data in excel tables using Data Explorer Add-in.

Problem:

Our Excel Table has following Data:

Month Month Name
1 January
1 January
1 January
2 February
2 February
3 March

And we want to remove duplicates to make the data-set look like this:

Month Month Name
1 January
2 February
3 March

 

In real world data-sets, we wouldn’t have few rows but lot’s of rows and doing it manually wouldn’t be the wisest option. With that in mind, let’s look for a few-clicks solution that can help us remove duplicates.

Solution:

If you haven’t already, download the Data Explorer add-in preview available for Excel 2010 & 2013. It can do a lot more than removing duplicates – it’s a great add-in and it’ll save you lots of time especially if your job involves discovering, cleaning and combining data for analysis purposes. After you’re done installing the add-in, use the steps below to remove duplicates in an excel column:

1. Open Data in Excel. Switch to Data Explorer Tab

2. For the purpose of the demo, I am assuming that you already have the data in excel file. If not, you can connect to other sources via the add-in.

3. Data Explorer add-in > Excel Data> From Table

4. After you’ve clicked on the From Table, a query editor will pop up:

5. Select both columns

(you can select both columns by: select first column > hold down the ctrl key and then click on second column)

6. Right click > Remove Duplicates

If you’ve not downloaded and installed the data explorer add-in for Excel 2010 & 2013, you can find Information about it here: http://office.microsoft.com/en-us/excel/download-data-explorer-for-excel-FX104018616.aspx 

Note:

1) URL to download the add-in may change in future

2) The steps that I described may also change because as of today the ad-in is in “preview” stage and things may change in future.
