+**Description:**
+This Script Include converts a Base64-encoded Active Directory (AD) Object GUID into its corresponding hexadecimal format.
+When importing AD objects from an on-premises directory using LDAP, the object GUIDs are typically stored in Base64 format.
+However, in OOB integrations such as the AD V2 Spoke, the GUID must be provided in hexadecimal format. 
+This Script Include bridges that gap by decoding the Base64 string and converting it into the required hex representation.
+
+**Usage:**
+Can be used in the LDAP Transofrm scripts to convert the base64 code to HEX code
+
+**Sample:**
+
+var base64Code ='ayn8QMpHEGezHQDdAQZi2g==';
+gs.print(new global.LDAP_AD_Utils().base64ToHex(base64Code));
+
+**Output:**
