+# ServiceNow Fix Script: Normalize "prod" Environment Using GlideFilter
+
+## Problem Statement
+
+In many ServiceNow environments, custom fields like `u_environment` on tables such as `change_request` often contain inconsistent variants of the same logical value, for example: `prod`, `PROD`, `Prod`,`PrOd`, `pRoD` etc.
+
+These inconsistencies cause:
+- Bad or inconsistent reports
+- Broken automation rules like BR or flow with condition
+- And, Poor data hygiene or dirty values
+
+---
+
+## Solution: Fix Script or Background Script Using GlideFilter
+
+We use **`GlideFilter`** with **case-sensitive matching** to securely identify inconsistent values to avoid multiple `if` conditions or regular expressions.
+
+---
+
+## Example
+
+Instead of writing custom logic with if statement like this:
+
+```javascript
+var env = gr.u_environment.toString().toLowerCase();
+if (env === 'prod' || env === 'prod ' || env === 'PROD' || env === 'PrOd') {
+    // Normalize
+}
+```
+
+You can simply write:
+```javascript
+var filter = new GlideFilter('u_environment=prod', 'envNormalize');
+filter.setCaseSensitive(false);
+if (filter.match(gr, true)) {
+    // Normalize
+}
+```
+
+## **How to Use**
+1. Go to **Scripts - Background** or **Fix Scripts**.
+2. Define the script using above glidefilter example shared.
+3. Click **Run Script**.
