How get columns name from sharepoint list

[3tsolutions]

I've been looking for a way to have the column names of a SharePoint list so that I don't have to type them manually; I didn't find ready-made solutions, so I decided to create a custom solution for the purpose.

I created a flow with power automate, which can be trigger from PowerApps, in which it is requested:

• the SharePoint site,
• the name of the list
• if you want all the columns or if you want to filter the reserved SharePoint columns

Step 1 ) Build an instant cloud flow and Choose how to trigger this flow with PowerApps

Step 2) Use Compose to ask in PowerApps 3 inputs:

• the SharePoint site,
• the name of the list
• if you want all the columns or if you want to filter the reserved SharePoint columns (filter_enable)

Step 3) Get items from SharePoint list and use the first two Compose Inputs , limit the count to 1 and choose to use all columns list

Then Create a CSV Table , using the list of elements

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

Step 4) Define the variables that we will have to use in the flow

1. The identification of CR

decodeUriComponent('%0A')​

• The headers of the CSV Table

first(split(body('Create_CSV_table'),outputs('Compose_NewLine')))​

• The string columns_name_filtered
• The string columns_name

Step 5) Let's check that the third input defines to enable column filters

If NO just set the variable columns_name with the headers

if YES we need to exclude all column names reserved by SharePoint

Step 6) For each headers

split(variables('headers'),',')

exclude the reserved name, than set the variable columns_name with a columns_name_filtered

substring(variables('columns_name_filtered'),0,sub(length(variables('columns_name_filtered')),1))

we use a substring to eliminate the comma at the end of the filtered string

Step 6bis) to exclude the names of the reserved columns we use a control in OR condition,

than append the filtered columns to the variable columns_name_filtered with a comma

concat(item(),',')

Step 7) finally we send the response to PowerApps

@3tsolutions Hi, I am new to power apps, How do we run this flow or how to call this flow from Powerapps

Thank you so much for posting this solution! I thought I'd throw in my adaptation of your solution which gives me the column names in the Flow a bit quick for a simple copy and paste: After the step that gets the "column names filtered" which gives the string with all items, I just added a new array variable that splits on the ',':

which when run gives us the internal column names in a list that's relatively easy to copy and paste into whatever formula:

Thanks for sharing this! 

I reviewed your method and was going to try it this way, but then I went down the rabbit hole of wondering if it was exposed via an endpoint, and sure enough, it is! Instead of using a CSV, I'll just use a SharePoint HTTP action, append array action to create the table of columns! If you like my 3-step flow, please mark it as a second solution! 

1. HTTP request to SharePoint:

   a. Site Address: team site URL, not root site URL

   b. GET

   c. URI: /_api/web/lists/getbytitle('LISTNAME')/fields?$filter=Hidden eq false and ReadOnlyField eq false

           - Also, the filter above takes care of all of the reserved columns except for "Content Type" and "Attachments", which could be removed by changing the URI to: /_api/web/lists/getbytitle('LISTNAME')/fields?$filter=Hidden eq false and ReadOnlyField eq false and Title ne 'Content Type' and Title ne 'Attachments'

2. Run the flow/perform this request to get a sample payload

3. Add Parse JSON step, using the body from the previous step and paste in the sample payload in the "Generate from sample" option

4. Append "Title" to an array variable inside of an Apply to Each loop based on "results"
