Excel users often need to perform simple mathematical operations such as subtracting one column from another. This task can be accomplished using Excel functions and formulas, but it can be tedious and time-consuming.
While Excel requires manual setup of functions, this guide will show you the steps and explore how Sourcetable, an AI-powered spreadsheet tool, lets you perform column operations instantly by simply chatting with an AI assistant. Sign up at Sourcetable to try it yourself and streamline your spreadsheet tasks.
To perform subtraction between two columns in Excel, use the formula =number1 - number2
. This basic arithmetic operation can be applied to subtract numbers, percentages, dates, and times across columns.
For subtracting numeric values, percentages, or dates, simply select the cell where you want the result and enter the formula with the cell references of the two columns you want to subtract. For instance, =A1 - B1
subtracts the value in column B from column A for the first row.
Use parentheses to specify the order of operations if your formula includes multiple arithmetic calculations. For example, =(A1 + A2) - (B1 + B2)
ensures that the sums of A1 and A2 and B1 and B2 are calculated before subtraction.
To subtract multiple cells from a single cell, utilize the SUM function in the formula, such as =A1 - SUM(B1:B5)
, to subtract the sum of a range in column B from a single cell in column A.
For time differences, the TIMEVALUE function can be used with the basic subtraction formula =End_time - Start_time
to calculate the difference between two times.
Subtract matrices using an array formula by inputting the subtraction formula and pressing Ctrl+Shift+Enter to confirm it as an array formula. For example, {=Matrix1 - Matrix2}
subtracts one matrix from another.
To subtract text strings, apply the SUBSTITUTE and TRIM functions to remove specific text. Then use the TRIM function afterward to clean up any extra spaces in the result.
Subtract one list from another by using the IF function to compare elements. This is useful for identifying items in one list that are not present in another.

Instead of manually creating charts in Excel, Sourcetable's AI can transform your data into stunning visualizations instantly. Simply tell the AI what type of chart or insight you want to see.
Sourcetable handles files of any size and connects directly to databases, eliminating Excel's size limitations. Upload CSV, XLSX files or connect your database, then let the AI analyze everything through natural conversation.
Unlike Excel's blank canvas, Sourcetable can generate entire spreadsheets from scratch, complete with sample data, based on your description to the AI. This eliminates hours of manual setup and formatting.
Sourcetable replaces Excel's complex menu systems and formula syntax with straightforward chat conversations. Tell the AI what you need, and it handles all the technical details automatically.
Use the minus formula for the topmost cell of the columns (e.g., =B2-C2), then drag the fill handle down to copy the formula to the rest of the column. The formula will automatically adjust for each row.
Use an absolute reference with the $ sign (e.g., =B2-$F$1), where F1 contains the number you want to subtract. The absolute reference prevents the reference from changing as you drag the fill handle down the column.
Use the SUM function with a formula like =SUM(B5:E5)-SUM(F1:F4) to subtract the sum of one column range from another column range.
Subtracting columns in Excel requires understanding formulas and cell references. While it's a fundamental spreadsheet skill, getting started can be challenging for new users.
