Reversing the sign in Excel can be useful in many situations. Find out here which functions can help you and how to implement them.
How to reverse the sign in Excel
The easiest way to reverse the sign in Excel is to use a simple mathematical operation.
- Multiplication by -1: To reverse the sign of a number, use multiplication by -1. In a new cell, type “=-1*A1”, where A1 is the cell containing the number you want to change.
- Using the SUM function: Use the SUM function to add multiple numbers with reversed signs. For example, “=SUM(-A1)” reverses the sign of the number in A1.
- Reverse negative signs: If you only want to convert negative signs to positive ones, use “=ABS(A1)”. This function returns the absolute value of the number, which is always positive.
Other useful Excel functions
There are other Excel functions that can help you change the sign.
- Function “VALUE”: The VALUE function allows you to convert text to numbers, which can be useful for negative numbers. Example: “=VALUE(A1)”.
- Function “IF”: With “IF” you can set conditions to reverse the sign only under certain circumstances. Example: “=IF(A1<0, ABS(A1), -A1)”.
- Using the SIGN function: This function returns the sign of a number. This can be useful in combination with other functions. For example, “=SIGN(A1)” returns -1, 0, or 1 depending on the sign of the number in A1.
Sign reversal in larger data sets
If you need to reverse multiple signs in Excel in a large table, you can use these methods.
- Autofill: Use AutoFill to copy the formula to adjacent cells. Simply drag the small square in the corner of the cell down or to the side.
- Using macros: Macros allow you to automate complex tasks. Create a macro that reverses the sign of a selected set of data.
- Power Query: For advanced users, Power Query can be used to manipulate large data sets and make sign changes.
