Replace double quote with single quote

[rob_danks]

I have written a Power App for a user to select multiple Purchase order numbers and then trigger a Flow. The Purchase order numbers are passed to the Flow as a JSON I have have then used the Replace function to create a string as follows.

PurchaseOrderNumber eq "PO510004" or PurchaseOrderNumber eq "PO510002"

I need to replace the double quotes with single quotes to be able to use the string as a filter in the D365 FinOps 'List items present in a table' action, but the Replace function doesn't allow this as the expression below results in 'The expression is invalid'.

replace(outputs('POFilter'),'"',''')

Can anyone advise of a way to do this?

There are a few different ways to do it, but here is an expression that will do it:

replace(outputs('Compose'), '"', decodeUriComponent('%27'))

change outputs('Compose') to whatever holds your filter string.

That worked a treat, many thanks.

had the same issue but the above wouldn't work for me, I had to actually distinguish left/right sided quote marks for some reason. 
in playing with a uri encoder i found this added info for each type of quote mark  note the differences in parenthseis (left“ neutral" right”) results in this:

left %E2%80%9C

neutral %22

right %E2%80%9D
