How do I use if and formula on a large amount of data without inputting every cell in the range?

To handle such a large dataset efficiently in Excel without manually inputting every cell, you can use a lookup function like VLOOKUP or INDEX/MATCH combined with nested IF statements. Here's how you can do it:

1. Sort the Tax Table: First, make sure your tax table is sorted in ascending order by the "Between" column.
2. Use VLOOKUP with Approximate Match: Since your earning falls within a range, you'll want to use VLOOKUP with approximate match. Here's how you can set it up:

=VLOOKUP(A2, Tax_Table!$A$2:$C$1000, 3, TRUE)

• Replace A2 with the cell containing the earning amount.
• Tax_Table!$A$2:$C$1000 should be replaced with the range of your tax table.
• 3 indicates the column from which to retrieve the withholding amount.
• TRUE specifies approximate match.
1. Nested IF Statement with VLOOKUP: To integrate this into your payroll sheet, you can use a nested IF statement:

=IF(A2="","",VLOOKUP(A2,Tax_Table!$A$2:$C$1000,3,TRUE))

• This formula assumes that the earning amount is in cell A2. Adjust it according to your actual cell reference.
1. Handle Edge Cases: Since VLOOKUP with approximate match might not handle all edge cases perfectly, you might need to adjust your tax table or add additional conditions to your formula to cover all scenarios.
2. Drag Down the Formula: Once you have the formula set up for one cell, you can drag it down to apply to the entire column.

By using VLOOKUP or INDEX/MATCH with nested IF statements, you can efficiently calculate the income tax for a large dataset without manually inputting every cell in the range. The text and steps were edited with the help of AI.
