Uploading attachment through transform Map

Aaviii · ‎12-26-2025

Hi,

I have a requirement to upload data through excel which contains column of attachment links. I want these attachments to be attached to the records inserted or updated.

@Aaviii

then this sample script in your onAfter transform script should work fine

I tested with this sample external URL and file got attached to incident record

So you can enhance it so that it picks target sysId using target.sys_id

var url = 'https://s24.q4cdn.com/216390268/files/doc_downloads/test.pdf'; // your download URL
var targetTable = 'incident'; // record table
var targetSysId = '79f8565afbb936100db5f8454eefdc40'; // record sys_id

var request = new sn_ws.RESTMessageV2();
request.setHttpMethod('GET');
request.setEndpoint(url);
// This creates sys_attachment + sys_attachment_doc on the fly
var attachmentSysId = request.saveResponseBodyAsAttachment(targetTable, targetSysId, 'downloaded_file'); // name without extension
var response = request.execute();

var httpResponseStatus = response.getStatusCode();
gs.debug("http response status_code: " + httpResponseStatus);

Output:

Not too much to go on from the above but; to upload data from Excel with attachment links and attach them to records in ServiceNow:

Prepare Excel File: Ensure your Excel has a column with attachment URLs.
Use Import Set: Create an import set table in System Import Sets > Load Data to load the Excel data.

Script to Attach Files: After loading the data, use a Business Rule or Script Include to download the files and attach them to the correct records.

Example script:

var attachment = new GlideSysAttachment();
var recordSysId = current.sys_id;  // Record to attach to
var attachmentUrl = current.attachment_url;  // URL from Excel

// Download and attach the file
var response = new GlideHTTPClient().get(attachmentUrl);
if (response.getStatusCode() == 200) {
    attachment.write('target_table', recordSysId, response.getResponseBodyAsString(), 'application/octet-stream', 'filename');
}

Run the Import: After transforming the data, run the import and the attachments will be linked.

Let me know if you need more help!

@Matthew_13 these files are not within the instance. These links redirect to external PDF's. I have tried converting files to "base64" format and used onAfter transform script. File is getting attached but showing blank after downloading.

Below is the script:-

var fileName = source.u_file_name;

var fileContentType = source.u_content_type;

var fileData = source.u_base64_data;

var sa = new GlideSysAttachment();

sa.write(target, fileName, fileContentType, fileData);

@Aaviii

so those links are for files within the instance?

what did you start with and where are you stuck?
