Hi @twister ,
Please refer to the steps below:
1\ This is test list . I will convert it to a PDF file. ‘app_no’ and ‘Task’ are ‘Single line of text’ columns’.

2\ Build an instant flow ‘TEST 38’.


// Content : Ask in Powerapps
// Generate form sample: [{"Title":"a","app_no":"a","Task":"a"}]

3\ Add a button control and set its onselect property to:
ClearCollect(Test,ShowColumns(Child1,"Title","app_no","Task"))
4\ Add this flow to canvas app. Add a button control and set its onselect property to:
TEST38.Run(JSON(Test))
// TEST38 is the flow
5\ The result is as follows:
