+# Auto-fill form from base64encoded data
+
+This widget automatically populates a form on service portal using base64-encoded JSON passed via a URL parameter. Use the variable name as key or for surveys use the sys_id of the [asmt_assessment_instance_question]
+
+## How to
+
+1. Create a new widget and add the server script and client controller from the *Survey or form filler widget.js* file
+2. Add the widget for example as a catalog item variable or add it anywhere on your survey taking page such as *take_survey*
+3. Encode json of form fields and values key-value pairs and add it as a parameter called data into your url
+4. Navigate to page and form autofills
+
+## To note
+For catalog items the variable name is the key, for surveys the key to use is the sys_id of the [asmt_assessment_instance_question]
+
+
+## Example usage
+
+```javascript
+var obj = {
+	is_this_a_replacement_for_a_lost_or_broken_iphone: "yes",
+	what_was_the_original_phone_number: "1234567980",
+	monthly_data_allowance: "Unlimited",
+	color: "red",
+	storage: "256",
+}
+
+gs.info(GlideStringUtil.base64Encode(JSON.stringify(obj)))
