SharePoint workflow formula to format a string...

I have a simple workflow where a value of a Managed Metadata column is copied to the Single Line of text column so I can use it in lookups. The problem is that oob it is copied with a guid and looks like this:

My First Item|7fa249c5-0fdf-421a-84d9-ab501a1815d0

Open in new window

Can somebody help me write a formula I could use in a workflow string builder to remove the pipe symbol and guid from this string?

Try this:

1) Find substring in string in which:

substring is just the pipe | character
string is your metadatafield_0 field
output: index1
2) Extract substring from string with length in which:

substring is your metadata_0 field from the current item
starting location is 0
end is the output of the first step (index1)
output: substring1

there is no really elegant out-of-the-box way as String manipulations are (unfortunately) very limited in SPD 2010.

Use the workflow to store the value inside of the string column. Then create a second column of type "Calculated Column" to use this formula:

You might want to install this workflow activity extensions - they provide additional string operations/actions:
