When creating Single and Multiple Textbox questions, you can validate how the responses are to be entered by respondents.
The Validate Text option is located in the list of features when creating or editing questions. In addition, this is available anytime the Add Comment Field option is enabled on Multiple Choice, Matrix, or Rating questions.
You can apply Text Validations on the following:
- Single Textbox
- Multiple Textbox (*All textboxes will have this validation)
- Multiple Choice (One or Multiple Answers allowed)
- All Matrix types
- Rating types
NOTE: The Numerical textbox does not have this feature since it only allows positive, whole numbers.
Once this feature is applied, you will click the dropdown menu to access the following parameters for the comment box. A second prompt menu opens for further validation options like date ranges, character lengths, etc.:
- don't validate comment text
- must be a specific length
- must be a whole number
- must be a decimal number
- must be a date (MM/DD/YYYY)
- must be a date (DD/MM/YYYY)
- must be an email address
Example - Date Validation:
You want respondents to enter a date that falls between specific time periods.
If you select the following option from the Text Format valdiation drop-down menu:
- a second prompt menu will open beside it. This is where you will type in the date ranges:
Text Format: Date (MM/DD/YYYY) between (MM/DD/YYYY) and (MM/DD/YYYY)
You can validate the following open-ended question types to require that respondents enter their answer(s) in a specific format:
- Single Textbox
- Multiple Textboxes
Validating the Answer Format
You can validate the Single Textbox or Multiple Textboxes question type to only allow answers that are formatted in a specific way.
To validate a textbox question:
- Click an existing question to edit it. Or, add a new Single Textbox or Multiple Textboxes question to the survey.
- Click the Options tab.
- Click Validate Answer for a Specific Format.
- Choose from the following validation options:
- A specific length - Respondents must enter an answer between a specific character range.
- A whole number - Respondents must enter a whole number within a specific number range.
- A decimal number - Respondents must enter a decimal number within a specific number range.
- A date (MM/DD/YYYY) - Respondents must enter a date in MM//DD/YYYY format, within a specific date range.
- A date (DD/MM/YYYY) - Respondents must enter a date in DD/MM/YYYY format, within a specific date range.
- An email address - Respondents must enter an email address. NOTE: There is no way to validate that respondents have entered a valid email address. It will only detect whether or not their answer is in the format of an email address.
- Click Save.
NOTE: Comment Box question types cannot be validated.
Only Allowing Numerical Data
You can quickly validate the Multiple Textboxes question type to allow only numerical data (positive whole numbers), and to reveal the option to require a fixed sum.

- The options to choose between MM/DD/YYYY and DD/MM/YYYY format will appear to the right. Select the preferred format.
- Customize the Date Validation Message to be specific about how respondents must format their answer.
