Enhancing Data Quality with Regex Validation: A quick guide

Regex validation is a powerful tool in SurveySparrow that allows you to ensure the accuracy and completeness of collected data, particularly when it comes to validating email addresses. By using Regular Expressions (regex), you can easily verify that respondents provide valid email addresses in your surveys. In this guide, we'll walk you through the process of setting up regex validation for email text input in SurveySparrow, helping you collect reliable data.

Setting Up Regex Validation for Email Text Input in SurveySparrow

1. Accessing the Survey Editor

   • Log in to your SurveySparrow account.
   • Navigate to the survey where you want to set up email validation or create a new survey.

2. Adding a Text Input Question

   • Once you are in the survey editor, add a new question by clicking on the "Add New Question" button.
   • Choose the "Text" question type from the available question types.
     
     

3. Enabling Validation Settings

   • After adding the text input question, click on the question to open the question settings panel on the right side.
   • Under the "Validation" section, toggle the switch to enable validation for the text input question.
     
     

4. Entering the Regex Pattern

   • In the validation settings, you will find an input field labelled "Pattern."
   • Enter the regex pattern for email validation in this field. A commonly used pattern for email validation is:

   ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$

   This regex pattern checks for the correct email format with a local part before the "@" symbol, followed by a domain part after the "@" symbol.
   
   

5. Customizing Error Messages (Optional)

   • If respondents enter an invalid email address that does not match the regex pattern, you can set a custom error message to provide feedback to the respondents.
   • Use the "Error Message" field to enter a user-friendly error message indicating that the email format is incorrect.
     
     

6. Save and Preview

   • Save the changes made to the text input question by clicking on the "Save" button.
   • Preview the survey to ensure that the email validation is working as expected.

Conclusion

By following these steps, you can easily set up regex validation for email text input in SurveySparrow. This will help you collect accurate and valid email addresses from respondents, making your data more reliable and useful for analysis.

Remember to always test the validation thoroughly to ensure it functions as intended before deploying your survey to respondents. Happy surveying!

Here's a rewritten version of the explanation for the regex pattern:

To provide a more detailed explanation of the regex pattern:

1. `(?=.*[a-z])`: This part of the pattern ensures that the match includes any character that is followed by a lowercase letter.

2. `(?=.*[A-Z])`: Similarly, this section ensures that the match includes any character followed by an uppercase letter.

3. `(?=.*\d)`: This part matches any character that is followed by a digit (a number).

4. `(?=.*\W)`: Here, we're looking for any character (excluding line breaks) that is followed by a symbol.

5. `.{8,}`: This section ensures that the length of the match is at least 8 characters, where the dot `.` represents any character.

6. `^` and `$`: The caret `^` at the beginning of the expression and the dollar sign `$` at the end, together make sure that the match starts at the beginning of a word and ends with the word. This means that only whole-word matches are allowed, and partial matches are not considered.

I hope this clarifies the regex pattern for you. If you have any further questions or need more information, feel free to ask!

3. Numeric Input

   Pattern:

   ^-?\d+$

   Description: This regex pattern validates positive or negative integers.

4. Positive Integer Input

   Pattern:

   ^\d+$

   Description: This regex pattern validates positive integers only (no negative numbers or decimals).

5. Decimal Number Input

   Pattern:

   ^-?\d*\.?\d+$

   Description: This regex pattern validates positive or negative decimal numbers (e.g., 3.14, -0.5).

6. Date (YYYY-MM-DD) Format

   Pattern:

   ^\d{4}-\d{2}-\d{2}$

   Description: This regex pattern validates dates in the format "YYYY-MM-DD" (e.g., 2023-07-25).

7. Date (MM/DD/YYYY) Format

   Pattern:

   ^\d{2}/\d{2}/\d{4}$

   Description: This regex pattern validates dates in the format "MM/DD/YYYY" (e.g., 07/25/2023).

8. Alphabetic Text

   Pattern:

   ^[a-zA-Z]+$

   Description: This regex pattern validates text containing only alphabetic characters (uppercase or lowercase).
   
   

9. Alphanumeric Text

10. Custom Pattern

    Pattern: (Replace `YOUR_PATTERN_HERE` with your desired regex pattern)

    ^YOUR_PATTERN_HERE$

    Description: This is a placeholder pattern that you can customize based on your specific validation needs.
