Split CamelCase String

[NGuill]

I am trying to automate the naming of a document as it is uploaded into SharePoint using the filename.  I've solved everthing I need except for the Title of the document.  The filename comes in the format of FA-38596-01_EmailNewWelcomeLetter_20190425  where the elements I need are split by the "_" character.  What I need help with is the second element (EmailNewWelcomeLetter). Is it possible using Flow to enter a space between each captialized word?  This element changes depending on the type of document.

Hi @NGuill 

Note: This is not the most efficient ways of doing this but it works. 

You can use the expression:

trim(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(variables('test'),'A',' A'),'B',' B'),'C',' C'),'D',' D'),'E',' E'),'F',' F'),'G',' G'),'H',' H'),'I',' I'),'J',' J'),'K',' K'),'L',' L'),'M',' M'),'N',' N'),'O',' O'),'P',' P'),'Q',' Q'),'R',' R'),'S',' S'),'T',' T'),'U',' U'),'V',' V'),'W',' W'),'X',' X'),'Y',' Y'),'Z',' Z'))

Please replace the highlighted part with the item that stores this value.

Hope this Helps!

Hi @NGuill ,

Could you provide a style that specifically describes the effect you want to render?

If you want to use "_" as a separator and get the second element, you can refer to the following expression:

If you want to replace "_" with a space, please refer to the following expression:

replace(variables('Title'),'_',' ')

Best Regards,

Thanks @yashag2255, for your help.  I agree this is not an elegant way, but it gets the job done.  I'd prefer a regex type of solution though.

Thanks @v-bacao-msft, but I had already stated that I had achieved splitting the text by "_".  I needed to insert a space before each capital letter in the second element.  Meaning I need the result to be "Email New Welcome Letter".

Hey @NGuill 

Yep. Regex is something that is a much needed feature. There have been some ideas created to include regex as a feature here

You can create a new one or UpVote the already created ones so that it reaches the product team. 

Hope this Helps!
