Filter Inputs

Remove all empty strings from a set of inputs.




input1, input2, etc.


Any number of input strings.




output1, output2, etc.

Output strings matching all non-empty inputs. For instance, suppose the inputs are:
input1="quick", input2="", input3="brown", input4="", input5="", input6="fox"

Then the outputs will be:
output1="quick", output2="brown", output3="fox"

The non-empty strings are moved up and the empty strings are skipped.


This action is typically used to display a variable amount of information neatly. For instance, suppose you have a checklist of photos and comments, and you want to add it to a form table. But you know that the checklist doesn't always have information in each row — for example, the checklist may have data in rows 1, 6 and 8, with the remaining rows empty. When adding this to the form, you want to consolidate this into 3 consecutive rows rather than leaving empty rows, so that it looks neater. The Filter Inputs action allows you to do this.
