Remove all empty strings from a set of inputs.
Any number of input strings.
Output strings matching all non-empty inputs. For instance, suppose the inputs are:
Then the outputs will be:
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.
