Substitute Certain Characters Before submitting values into SharePoint

[lliu_western]

Hello Community,

I have a form in PowerApps. The data on the form is submitted to SharePoint by clicking a save bottom.

The function goes:

OnSelect    -  SubmitForm(EditForm1)

PowerAutomate then kicks in to take all the values/column values from SharePoint and convert them into JSON then talk to API. 

The issue I am having is that I don't know when a user will type some characters in whichever field in the form and the character will break the JSON.

Is there any way I can update the form before the SubmitForm(EditForm1) action so all the data in the form doesn't contain any character that will break JSON?

Any advice will be great appreciated!

Hi @lliu_western ,

You should be able to do this in the Update property of the card the control is contained in.

Hi, @WarrenBelz , thank you for your reply.

I am trying it with the Update property now, but it seems like only allow me to use substitute with one value. Is it possible to substitute many special characters into one single value?

I am thinking of a function like  Substitute(DataCardValue17.Text,[Char(10), "$", "@", "!"],"-")

So have a nested values that I want it to replace of?
