In this Excel tutorial, I’ll present you use Power Query’s Extract and Split Column options to extract delimited strings into their elements. I’m utilizing Microsoft 365 Desktop and Power Query in Microsoft Excel. Power Query is offered in older variations by means of Excel 10. You can obtain the Microsoft Excel demo file for this tutorial.

Why it is best to use Excel’s Power Query

You can use Excel string features, Text to Columns or Flash Fill, however listed below are causes you may not:

  • Text to Columns writes over the unique knowledge.
  • Your knowledge may not be in Excel, as though Power Query is offered in Excel, Power Query can import knowledge from a lot of sources — not simply Excel.
  • The supply knowledge incorporates extra rows which you can import into Excel.
  • You may want to make use of Power Query for one thing way more complicated and extracting a subset of the unique entry is simply step one.

If the info is in Excel, you may use features or formulation, however except you’re an skilled, that can take a little bit of time. Most of us can’t simply rattle off the mandatory syntax and get it proper the primary time. Power Query is fast and requires no specialised information of Excel features.

How to get the info into Power Query

We’ll be working with a easy Excel sheet with a couple of delimited strings in a Table named TableCustomerID. You don’t have to exchange the default Table identify, however significant names are simpler to work with in case you have a number of Tables.

Let’s suppose you could have an inventory of buyer identification numbers with three sections every. Furthermore, a hyphen character serves as a delimiter between the three sections (Figure A). You need to use the center element of every string as a result of that’s the part that really identifies every buyer. The different two elements establish the area the place the client resides and a transaction quantity.

Figure A

Load the Excel data into Power Query.
Load the Excel knowledge into Power Query.

The first step is to load the info into Power Query as follows:

1. Click anyplace contained in the Table.

2. Click the Data tab.

3. In the Get & Transform Data group, click on From Table/Range.

That’s it. The easy Table proven in Figure A is now in Power Query.

With the info in Power Query, you can begin extracting sections.

How to extract delimited strings utilizing Extract choices in Power Query

There are actually two methods to extract knowledge in Power Query. We’ll start by utilizing Extract choices, which returns a subset of the unique worth. To accomplish that, click on the Transform tab after which click on the Extract dropdown within the Text Column group.

As you may see in Figure B, there are a number of choices and so they’re all self-explanatory for probably the most half. We’re going to take a look at the delimiter choices so you may see what every one does.

Figure B

There are several Extract options.
There are a number of Extract choices.

After clicking the header of the Customer ID subject to pick the column, click on the Transform tab, if mandatory after which click on Extract within the Text Column Group. Choose the Text Before Delimiter possibility. In the ensuing dialog, enter the hyphen character (Figure C) and click on OK.

Figure C

Enter the hyphen character as the delimiter.
Enter the hyphen character because the delimiter.

As you may see in Figure D, this feature returns solely the primary character(s) earlier than the delimiter.

Figure D

This option returns only one character for each string.
This possibility returns just one character for every string.

To reclaim the unique knowledge, delete the Extracted Text Before Delimiter step within the Applied Steps pane proven in Figure E.

Figure E

Simply select it and press Delete.
Simply choose it and press Delete.

Now, let’s do the identical factor with the following possibility, Text After Delimiter. When prompted, enter the hyphen character and click on OK to see the outcomes proven in Figure F. This time, Power Query removes the primary two characters, the primary quantity and the primary hyphen.

Figure F

This option returns all the characters after the first hyphen character.
This possibility returns all of the characters after the primary hyphen character.

Once once more, reclaim the unique knowledge by deleting the extract step after which select the Text Between Delimiters possibility. This time, Power Query prompts for provide two delimiters. In this case, they’re each the hyphen character (Figure G).

Figure G

Enter both the start and end delimiter.
Enter each the beginning and finish delimiter.

Click OK to see the outcomes proven in Figure H.

Figure H

The last option returns the characters between the two hyphen characters.
The final possibility returns the characters between the 2 hyphen characters.

Now we’ll have a look at one other option to divide the three sections of every string, however we received’t extract items from the strings, we’ll break up the strings. Reclaim the unique knowledge earlier than you proceed.

How to extract delimited strings utilizing Split Column in Power Query

Power Query’s Split Column helps you come greater than a single piece of the string. For occasion, let’s suppose you need three columns of information, one for every part. To accomplish this, use Split Column as follows:

1. After choosing the column, click on the Home tab.

2. In the Transform group, click on Split Column.

3. Click the primary possibility, By Delimiter.

4. In the ensuing dialog, you don’t must do a lot as a result of Power Query does an excellent job of discerning your wants. Make positive Power Query selects Each Occurrence of the Delimiter within the Split At part (Figure I).

Figure I

Choose the option that uses all the delimiter characters.
Choose the choice that makes use of all of the delimiter characters.

5. Click OK to see the ends in Figure J.

Figure J

This option separates the three sections into three columns.
This possibility separates the three sections into three columns.

This possibility separates every string into three columns utilizing the delimiter character to find out the place every part begins and ends.

As you may see, each Extract and Split Column assist you separate knowledge rapidly. You’re more likely to run into makes use of for each.
