1. What is the TEXTJOIN Function & Why is it Superior?
The TEXTJOIN function is modern Excel's premier formula for stitching multiple cells and ranges together. It solves the two biggest headaches of old concatenation methods:
1) It inserts a uniform delimiter (like ", ") between every cell automatically.
2) It has a built-in ignore_empty boolean parameter that skips blank cells, preventing double commas (e.g. "John,, Smith")!
