The textjoin function in Microsoft Excel is a powerful tool that can be used to combine text from multiple cells into a single cell. The function can be used to join text strings together, making it easy to create lists or other types of text quickly and efficiently.

To use the textjoin function, start by selecting the cells that contain the text you wish to combine. Once the cells are selected, type in the formula “=TEXTJOIN("",true,[cell1,cell2,etc])”. Replace "cell1, cell2, etc" with the cell references of the cells you want to join. The “true” argument can be replaced with “false” if you don't want to include leading spaces.

The textjoin function can also be used to combine numbers. To do this, add an extra argument inside the parentheses. For example, if you wanted to combine the numbers in cells A1, B1, and C1, you would use the formula “=TEXTJOIN(",",true,[A1,B1,C1],1)”. The "1" argument tells Excel to treat the cells as numbers instead of text.

In conclusion, the textjoin function in Microsoft Excel is a useful tool for combining text from multiple cells into a single cell. By understanding how to use the textjoin function correctly, you'll be able to quickly and easily create lists or other types of text.
