Split string transform function


The split string transform function is used to split elements of a string into an array, with a user-defined delimiter. For example, you might have product data in a string:


...and need to convert these items to an array before pushing to the destination system:

  "fruit_out": [

In this case, items in our source string value are delimited with a comma, so we can use this to determine where each split occurs. The transform checks incoming string values and determines each array item to be the word after each comma.

Adding a split string transform

Step 1 In your process flow, access settings for your map shape:

Step 2 Select the add transform icon for the required mapping rule - for example:

Step 3 Click the add transform button:

Step 4 Click in the name field to access a list of all available transform functions, then select split from the string category:

Step 5 In the delimiter field, enter the character that delimits elements in the string:

If you use any of the following characters, they should be escaped: . + * ? ^ $ ( ) [ ] { } | \ /

For example, a delimiter of * would be entered as:


A space is a valid character.

Step 6 Click the add field button:

Step 7 Click in source fields and select the source field to be used for this transform:

Step 8 Accept your changes (twice).

Step 9 Save the transform. You'll notice that the transform icon is updated to indicate that a transform function is present for the mapping row - for example:
