How-to Guide
1. Create a drop-down list
Entry: Data tab → Data Validity

- Click Data Validity on the Data tab.
- Set the validation Condition.
- Select options such as Ignore blank and Apply these changes to all other cells with the same settings as needed.
- Click OK. When you select the target cell again, a drop-down arrow appears.
Success Criteria
- Interface result: A drop-down arrow appears in the target cell.
- Next action available: You can choose from preset options to complete data entry.
Tips While Using

- Environment note: You need permission to edit the target cells.
2. Set a value range limit
Entry: Data tab → Data Validity
- Select the cell range where you want to limit input values.
- Open the Data Validity dialog box.
- In the Allow list, choose a type such as whole number, decimal, date, or time.
- Set the minimum and maximum values.
- On the Error Alert tab, configure the message shown when the rule is not met.
Success Criteria
- Interface result: The target range keeps the saved value-limit rule.
- Next action available: Entering a value outside the allowed range triggers the configured prompt.
Tips While Using
- Common mistake: Reversing the minimum and maximum values can make the rule behave unexpectedly.
- Environment note: The selected rule type should match the kind of content entered in the cells.
3. Set input messages and error alerts
Entry: Data Validity dialog box → Input Message / Error Alert tabs
- Open the Data Validity dialog box.
- Switch to the Input Message tab and set the title and message shown when a cell is selected.
- Switch to the Error Alert tab and set the alert style and message for invalid input.
- Click OK to save the settings.
Success Criteria
- Interface result: An input message appears when the cell is selected, and an alert appears when entered data does not match the rule.
- Next action available: Users can correct their input based on the prompt.
Tips While Using
- Common mistake: Setting the rule without adding guidance text can leave collaborators unsure about what to enter.
- Environment note: These prompts are saved with the file and apply to the related cells.
