+## ServiceNow Fix Script: Remove Extra Spaces
+A generic ServiceNow fix script to clean data by removing extra whitespace from any specified field on any table.
+
+### Problem It Solves
+This script resolves data integrity issues caused by inconsistent user input, such as:
+- Leading or trailing spaces (e.g., " Hello World ").
+- Multiple spaces between words (e.g., "Hello   World").
+  
+### How to use
+1. Create and Configure the Fix Script
+    - First, create a new Fix Script in your ServiceNow instance (**System Definition > Fix Scripts**) add past the code
+
+2. Add your table name and field that you want to clean up
+    - Before running, you must update the following variables inside the script to define your target:
+      ```js
+      var tableName = 'incident'; // <-- CHANGE THIS to your table name
+      var fieldName = 'short_description'; // <-- CHANGE THIS to your field name
+      ```
+
+3. Change `processRecords` value and run
+    - To see what changes will be made without actually updating records, ensure the `processRecords` variable in the script is set to `false`
+      ```js
+      var processRecords = false;
+      ```
+    - To actually do the update, change the `processRecords` variable to `true` and run the script
+      ```js
+      var processRecords = true;
+      ```
+
+4. Run the script

+ * Fix Script: Remove Extra Spaces from a Field
+ *
+ * Description:

+ * INSTRUCTIONS:
+ * 1. Update the tableName and fieldName with the table and field you want to remove spaces from, usually fieldName will be name or short_description
+ * 2. Set 'processRecords' to false for a preview, set to true to do the updates
