How to Prevent a Nested IF Formula from Returning FALSE for Blank Cells in WPS Office Spreadsheets
Question details
The user needs a WPS Office Spreadsheets formula that tests the referenced cell for blank content before calculating a difference, so an unhandled blank cell returns an empty string instead of FALSE.

- Product
- WPS Office Spreadsheets
- Device & OS
- not provided
- Scenario
- The user is building or correcting a nested IF formula where C3-C2 should calculate only when A3 contains a value; otherwise the formula must gracefully handle the blank cell.
- Observed behavior
- The formula returns FALSE when A3 is blank because the first condition does not explicitly handle an empty cell.
Open the workbook in WPS Office Spreadsheets and locate the formula cell. Identify the referenced cell that must be tested for blank content before the calculation runs.
Rewrite the Formula to Test for Blank A3 First
Use this solution when the formula should display an empty cell instead of FALSE whenever A3 is blank.
The formula =IF(A3="","",C3-C2) checks A3 before performing the subtraction. If A3 is blank, the formula returns an empty string; otherwise it returns the difference between C3 and C2.
Click the cell that currently returns FALSE, then click inside the Formula Bar or press F2 to edit the formula.
Replace the existing formula with =IF(A3="","",C3-C2). This explicitly returns an empty string when A3 is blank.
Press Enter to apply the formula. If the same logic is needed in other rows, drag the fill handle down or double-click it to copy the formula.
Use ISBLANK for an Explicit Blank-Cell Check
Use this alternative when you prefer a dedicated blank-cell function and want your formula to clearly test for a truly empty cell.
Fix Nested IF FALSE Results for Blank Cells in WPS Office Spreadsheets
WPS Office Spreadsheets uses the same IF formula syntax as Microsoft Excel, so you can add a blank-cell test such as =IF(A3="","",C3-C2) directly in WPS and keep your workbook compatible.
- 1. Open the workbook in WPS Office Spreadsheets: Launch WPS Office, click Spreadsheets, and open the workbook that contains the nested IF formula.
- 2. Select the formula cell: Click the cell that currently returns FALSE, then click in the Formula Bar to edit it.
- 3. Enter the blank-cell test: Type =IF(A3="","",C3-C2) and press Enter. Adjust A3, C2, and C3 to match the cells in your workbook.
- 4. Copy the correction: Use the fill handle to copy the formula to the remaining rows that need the same blank-cell logic.
- 5. Save as an Excel-compatible format: Click Menu > Save As and choose .xlsx to keep the workbook compatible with Microsoft Excel.

Frequently Asked Questions
Why does my IF formula show FALSE instead of a blank cell?
The formula is missing a blank-cell branch. In WPS Office Spreadsheets, use =IF(A3="","",C3-C2) so a blank A3 returns an empty string instead of FALSE.
Should I use ="" or ISBLANK(A3) to test for blank cells?
Use =IF(A3="","",C3-C2) when you want to treat both empty cells and formula-generated empty strings as blank. Use =IF(ISBLANK(A3),"",C3-C2) when you only need to detect truly empty cells.
Can I return 0 instead of blank when A3 is empty?
Yes. Use =IF(A3="",0,C3-C2). WPS Office Spreadsheets will display 0 whenever A3 is blank.
How do I apply the corrected formula to an entire column?
Enter the formula in the first row, then double-click the fill handle or drag it down to copy the formula to the remaining cells in the column.
