Yes, you can start the numbering on row 2 by using a formula in a new column. Here are the steps:

1. Insert a new column to the left of the column you want to number.
2. In the first cell of the new column (B2, assuming your data starts in A1), enter the formula "=ROW()-1". This will subtract 1 from the row number, effectively starting the numbering at 1 for row 2.
3. Copy the formula down the column by selecting the cell with the formula, then dragging the fill handle (the small square in the bottom right corner of the cell) down to the last row of your data.

Now you should have a new column with the row numbers starting at 1 for row 2. You can hide the original row numbers column if you don't want to see both sets of numbers.
