Forms to Planner flow - user submits checklist text that is too long

Posted on by annie2

I built a Power Automate flow from a Form to Planner. The Form is for employees at my company to fill in and I ran into this issue:

1. You cannot limit the free text fields on MS Forms to a custom character limit so sometimes people submit things that are too long

2. Checklists in Planner have a 100 character limit

3. If the user submits something longer than that in the Form it breaks the flow and the Planner card is empty

My question is, can I write a condition to say "if the characters entered is greater than 100 display N/A"?

the error if the characters submitted exceeds 100

@annie2 you can definitely write a condition and check the length of the submitted text with the below and return any value you'd like

length('your string')

but it's probably better to add a condition to return the first 100 characters with the substring expression if the length of the input exceeds 100 characters.

substring(text: string, startIndex: integer, length?: integer)

here's an example of how you can do it.
obviously replace the 'outputs('Compose_2')' with your control.

realised I didn't include the code I used in the yes branch
substring(outputs('Compose_2'),0,100)

If you found this response useful, give it a thumbs up and don’t forget to mark your post answered to help others find the solution easier.

I didn't do this exactly but I did use the substring function to shorten the checklist item and that worked, thank you!

@annie2 that's great. the only reason I was suggesting checking the length is because the flow will throw an error if the string is less than the length you specify in the substring

Ahhh yes I see that now - is there any way to make it <= a certain amount of characters?

yes, with the condition I posted above. use length('your string input') greater than or equal to/less than or equal to. then do the action on the yes/no branch. it's up to you how you construct the logic. hope this helps.
