📄 Duplicate Record Finder (ServiceNow Server-Side Script)

🧩 Description

This script helps identify duplicate records within any table and field in a ServiceNow instance. Using the GlideAggregate API, it performs a grouped query to find values that appear more than once, making it a useful utility for administrators and developers focused on data quality and integrity.

The script includes basic input validation and outputs a clean summary of the duplicated values along with their counts.

• ✅ Works on any table and field
• ✅ Fast and efficient using GlideAggregate
• ✅ Validates input parameters

• ✅ Designed to run as a Script Background or Fix Script

🛠️ Usage

🔧 How to Run

1. Go to System Definition > Scripts - Background

3. Replace the input variables:

   var tableName = 'incident'; // Change this
   var fieldName = 'caller_id'; // Change this

4. Click Run Script

Hi @Shweyy123
As per the guidelines, please add a README file as well. It should provide more details about the use case and the code you’ve written.

Hi @Atul-LNG ...
The description i have provided is the readme file.. Whether it is wrong

[Atul-LNG]

Hi @Shweyy123
Appreciate your response. However, a README file is required for the code snippet. The description alone is not a replacement for the README.

Please copy the content from the description into a proper README file. If any changes are needed, make those as well, and then resubmit.

Hi @Shweyy123

It seems there’s some confusion. I didn’t ask you to attach the file separately — you need to check that the README file is included along with the JS file in your submission. It should show here.
