How to select data from an array based on dynamic column and row headers

I have created a flow that runs when a form is completed.

 

I would like to use two of the choices in the form to select a value from a sharepoint list.

 

I can select the row using 'Get Items' and applying a Filter Query where '["Choice1"] eq [Column1]'

 

This allows me to hardcode the output value I wish to use.

 

What I would then like to do, is dynamically return a value from a column as specified by "Choice2"

Hopefully this is what you are after.

 

I'm using the following list for this example. Note that all columns are of type Single line of text.

And the following Microsoft Form.

grantjenkins_1-1670324162609.png

 

 

I'm providing two different flows here as it depends on how your internal column names get generated in your SharePoint List.

 

Assuming the internal names of your SharePoint columns match the names you have in your Microsoft Form, we would do the following.

grantjenkins_2-1670324186880.png

 

Get items will retrieve the rows where the Title (in my example) is equal to the Area that was selected in the Microsoft Form. This should only return a single item, but will still be in an array as Power Automate doesn't know how many items would be returned.

Compose Output uses the following expression to extract out the value of the column we selected in our Microsoft Form.

//Note that r384d1b0fd9b14f4d83145371b5c50f6d in this instance is referring to the Field we selected in the Microsoft Form.

first(outputs('Get_items')?['body/value'])?[outputs('Get_response_details')?['body/r384d1b0fd9b14f4d83145371b5c50f6d']]

 

The expression first will get the first (only) item that was returned and pass in the Field that was selected in the Microsoft Form as the field name.

And that's it.

 

HOWEVER, this will work ONLY if the internal column names in your SharePoint List match what you have in your Microsoft Form, but often this is not the case. In my example, SharePoint actually named my columns Cat1, Cat2 and Cat3 very differently. To check what the internal names are, you can add a Compose directly after Get items and pass in the value, then run your flow. In the JSON output you will see what the internal names are. In my case, the three columns were named as shown below.

We definitely don't want to have these names in our Microsoft Form for users to choose, so we can instead, setup a mapping object. See full flow below for this scenario.

grantjenkins_6-1670324732689.png

 

Get items is exactly the same as the previous flow.

grantjenkins_7-1670324761987.png

 

Compose Map contains an object where the Property names match what we have in our Microsoft Form and the Property values are our internal column names.

{
  "Team": "Team",
  "Cat1": "OData__x0043_at1",
  "Cat2": "OData__x0043_at2",
  "Cat3": "OData__x0043_at3"
}

grantjenkins_8-1670324855150.png

 

Compose Field uses the following expression to return the internal column name using the Microsoft Form Field name. This will give us the internal column name that we can use in the final Compose.

outputs('Compose_Map')?[outputs('Get_response_details')?['body/r384d1b0fd9b14f4d83145371b5c50f6d']]

 grantjenkins_10-1670325044162.png

 

Compose contains the expression similar to the previous flow, but instead of passing in the Field from the Microsoft Form, it passes in the internal column name retuned from Compose Field.

first(outputs('Get_items')?['body/value'])?[outputs('Compose_Field')]

Hello @LCCmikecollier , Are we trying to Get Items where Column value matches either Choice1 or Choice2? If Yes, Column eq 'Choice1' or Column eq 'Choice2' should work.

Please share the flow screenshot and clarify more on requirement If I misunderstood the requirement.

 

Hi @Ajinder31,

 

Choice1 is a list of areas (North, East, South, West)

Choice2 is a list of Categories (Team, Cat1, Cat2, Cat3...)

 

The list is designed as below:

AreaTeamCat1Cat2Cat3
North    
East    
South    
West    

 

Step 1) Get Items for Choice1 eq 'Area' and returned the value in the 'Team' column by selecting it from dynamic content

 

Step 2) Dynamic lookup where if Choice1 = North and Choice2 = Cat2, it would return the value in (North, Cat2)...

 

As I am always going to be doing Step 1, I thought that it may be able to just do a filter on the existing Get Items. It's all being pulled into an automatic email via Send a email (v2). I thought that I may be able to do it via an expression or a Filter Array.

Hopefully this is what you are after.

Whether you're just getting started or you're a seasoned pro, Tuesday Tips will help you know where to go, what to look for, and navigate your way through the ever-growing--and ever-changing--world of the Power Platform Community!

The best way to make sure you know what's going on in the News & Announcements, to blogs you follow, or forums and galleries you're interested in is to subscribe! These subscriptions ensure you receive automated messages about the most recent posts and replies. Even better, there are multiple ways you can subscribe to content and boards in the community! (Please note: if you have created an AAD (Azure Active Directory) account you won't be able to receive e-mail notifications.)   Subscribing to a Category  When you're looking at the entire category, select from the Options drop down and choose Subscribe.     You can then choose to Subscribe to all of the boards or select only the boards you want to receive notifications. When you're satisfied with your choices, click Save.     Subscribing to a Topic You can also subscribe to a single topic by clicking Subscribe from the Options drop down menu, while you are viewing the topic or in the General board overview, respectively.     Subscribing to a Label Find the labels at the bottom left of a post.From a particular post with a label, click on the label to filter by that label. This opens a window containing a list of posts with the label you have selected. Click Subscribe.     Note: You can only subscribe to a label at the board level. If you subscribe to a label named 'Copilot' at board #1, it will not automatically subscribe you to an identically named label at board #2. You will have to subscribe twice, once at each board.   Bookmarks Just like you can subscribe to topics and categories, you can also bookmark topics and boards from the same menus! Simply go to the Topic Options drop down menu to bookmark a topic or the Options drop down to bookmark a board. The difference between subscribing and bookmarking is that subscriptions provide you with notifications, whereas bookmarks provide you a static way of easily accessing your favorite boards from the My subscriptions area.   Managing & Viewing Your Subscriptions & Bookmarks To manage your subscriptions, click on your avatar and select My subscriptions from the drop-down menu.     From the Subscriptions & Notifications tab, you can manage your subscriptions, including your e-mail subscription options, your bookmarks, your notification settings, and your email notification format.     You can see a list of all your subscriptions and bookmarks and choose which ones to delete, either individually or in bulk, by checking multiple boxes.     A Note on Following Friends on Mobile Adding someone as a friend or selecting Follow in the mobile view does not allow you to subscribe to their activity feed. You will merely be able to see your friends’ biography, other personal information, or online status, and send messages more quickly by choosing who to send the message to from a list, as opposed to having to search by username.
