Capitalize first letter

I have an action that gives me a first name, but I'd like to capitalize the first letter to make it more formal for automated email messages.  I know of toUpper, but I'm not sure how to make it only toUpper the 1st index (the first character) and nothing else.

 

Right now, I have a compose that can be called via outputs('HTML_TO_TEXT_PARSE').

 

I'm able to grab the first name by doing first(split(outputs('HTML_TO_TEXT_PARSE'),'.')) but cannot figure out how to capitalize ONLY the FIRST letter.

 

Flow does the following:

email comes in >> first.last@domain.com >> flow pulls out everything from the beginning of the string until the period >> first >> I'm failing to capitalize the "f" in "first"

Hi @admincaleb ,

 

Please try to use this expression:

Expression reference:

concat(first(toupper(split(outputs('Compose'),'.')[0])),substring(split(outputs('Compose'),'.')[0],1,sub(length(split(outputs('Compose'),'.')[0]),1)))

Found a previous post and used this:

 

concat(first(toupper(outputs('HTML_TO_TEXT_PARSE_FIRSTNAME'))),substring(outputs('HTML_TO_TEXT_PARSE_FIRSTNAME'),1,sub(length(outputs('HTML_TO_TEXT_PARSE_FIRSTNAME')),1)))

I had tried it prior to starting this thread, but flow wouldn't take it.  After about 5 page refreshes it finally took and works fine.

 

Thank you for the responses.

Hi @admincaleb 

 

Please refer this post

 

https://powerusers.microsoft.com/t5/Building-Flows/Split-string-into-array-of-characters-empty-delim...

 

This will convert your string to array. Then update the first index using toUpper expression. Finally convert the array back to string using concat.

 

Thanks

Hi

Let's assume you have stored the string you want to capitalize its first letter in a variable called 'currentString'

 

If so, I would combine first, skip, toUpper, and concat functions as follows:

concat(toUpper(first(variables('currentString'))),skip(variables('currentString'),1))

 

Hope this helps
