Hello AlanFarthing,
I'm Shalom and I'd happily help you with your question. In this forum, we are Microsoft consumers just like yourself.
I understand that you want to drag a formula without inserting column names in the blank cells. This is a known issue that occurs when you drag a formula across multiple columns that have no data in the first row. Excel automatically fills the first row of the blank columns with the column names, such as Column1, Column2, etc. This can cause problems when you save the file as CSV, as the column names will appear as invalid values.
There are some possible solutions that you can try to avoid this issue. One solution is to insert a blank row above the first row, and then drag the formula across the columns. This way, Excel will not fill the blank cells with the column names, and you can delete the blank row later. Another solution is to use the Fill command instead of dragging the formula. You can do this by following these steps:
Select the cell with the formula and the adjacent cells you want to fill.
Click Home > Fill, and choose either Down, Right, Up, or Left.
Excel will fill the selected cells with the formula without inserting the column names.
I hope this helps you to drag a formula without affecting the blank cells. If you need more help, please feel free to ask me.
Best Regards,
Shalom
