Hi

I'm using an AI agent to collect customer details to pass into an agent script.  The native results pass in all lower case and I can capitalise all by using upper(Flow.x) but cant get the correct syntax to capitalise the first letter using the usual 0,1 after the variable.  Is this at all possible please

Hi Philip,

Yes, this is possible. I tested it in Architect using Substring() and Upper().

If your slot value is stored in Task.text, the following expression capitalizes just the first letter while leaving the rest of the text unchanged:

Upper(Substring(Task.text, 0, 1)) + Substring(Task.text, 1, Length(Task.text) - 1)

It works by:

• Substring(Task.text, 0, 1) extracts the first character.
• Upper(...) converts that character to uppercase.
• Substring(Task.text, 1, Length(Task.text) - 1) returns the remainder of the text.
• The + concatenates the two parts together.

For example:

• software → Software
• john → John

This worked in my testing. If you need to capitalize every word (for example, john smith → John Smith), that would require a different approach.

Hope this helps.
