1. Is this request related to a challenge you're experiencing? Tell me about your story.

The template conversion module is no longer able to handle null values, which has caused my majority of parallel workflows to break; for each parallel section, I have to add a code module to generate a null string and add an aggregator variable to combine them. This is not very elegant.

2. Additional context or comments

the past:

I hope that the template conversion and LLM module can automatically detect and handle empty cells.
