Use Conditional Formatting to Identify Inputs, Formulas, Links, and Errors in WPS Office Spreadsheets
Question details
The user wants to apply conditional formatting rules to visually distinguish hard-coded inputs, formulas, external references, notes, and errors in a spreadsheet model without reducing readability.

- Product
- WPS Office Spreadsheets
- Device & OS
- not provided
- Scenario
- Building or reviewing an Excel-compatible workbook model that requires clear visual identification of different cell types.
- Observed behavior
- Using many colors can make the workbook harder to use, and some cell types such as external links are not reliably exposed by standard worksheet formulas.
Open the workbook in WPS Office Spreadsheets and identify the ranges you need to format. If possible, separate input, calculation, and output areas first so you can apply fewer conditional formatting rules.
Create formula-based conditional formatting rules to identify formulas and errors
Best for most models because it uses built-in functions and keeps the number of colors low.
Formula-based rules evaluate relative to the active cell in the selected range, so enter the top-left cell reference in the formula.
Select the cells you want to format, such as A1:D100, then go to Home > Conditional Formatting > New Rule.
In the New Formatting Rule dialog, choose Use a formula to determine which cells to format.
In the formula box, type =ISFORMULA(A1) and click Format to choose a fill color, then click OK.
Repeat the steps and enter =ISERROR(A1) to highlight errors with a different format.
Click Home > Conditional Formatting > Manage Rules to check the rule range, order, and priority.

Identify hard-coded inputs and external references with helper formulas
Use when you also need to mark constants or external workbook references, especially in complex workbooks.
Separate input, calculation, and output areas before applying colors
Use to reduce visual clutter and avoid excessive conditional formatting rules.
Highlight Inputs, Formulas, Links, and Errors with WPS Office Spreadsheets
WPS Office Spreadsheets includes formula-based conditional formatting with functions like ISFORMULA and ISERROR, so you can clearly identify cell types in Excel-compatible workbooks without extra cost.
- 1. Open your workbook: Launch WPS Office Spreadsheets and open the .xlsx workbook you want to format.
- 2. Create a formula rule: Select the target range, then click Home > Conditional Formatting > New Rule.
- 3. Add ISFORMULA: Choose Use a formula to determine which cells to format and enter =ISFORMULA(A1).
- 4. Set formatting: Click Format, pick a fill color, and click OK to apply the rule.
- 5. Add error and link rules: Repeat for =ISERROR(A1) or use a helper formula for external links, then review under Home > Conditional Formatting > Manage Rules.

Frequently Asked Questions
Can WPS Office use ISFORMULA in conditional formatting?
Yes. Select the range, go to Home > Conditional Formatting > New Rule, choose Use a formula to determine which cells to format, and enter =ISFORMULA(A1).
How do I highlight only hard-coded input cells?
Use a formula-based rule with =NOT(ISFORMULA(A1)) for the selected range, or manually format a clearly separated input area with a static fill color.
Why are external links not highlighted by a standard conditional formatting rule?
Standard worksheet formulas do not reliably expose every link type. Use a helper column with FORMULATEXT and search for '[' or use VBA for complete external reference detection.
How can I avoid too many colors in a spreadsheet model?
Separate input, calculation, and output areas first. Use one or two conditional formats for dynamic states and static cell styles for fixed inputs, then add a legend.
Does this conditional formatting method work in Microsoft Excel and WPS Office?
Yes. Formula-based rules using ISFORMULA and ISERROR work in both WPS Office Spreadsheets and Microsoft Excel when the file is saved in .xlsx format.
