How to Add an Attachment Field to a Smartsheet Form

Use this interactive demo to learn how to add a file upload field to your Smartsheet form.

Quick summary

Adding an attachment field to a Smartsheet form lets respondents upload files directly through the form by inserting a File Upload element from the Form Elements panel and saving the updated form configuration.


Steps

  1. In Smartsheet's form editor, navigate to the left-side panel and select File Upload under the Form Elements section.
  2. In the Field Settings pane, enter your preferred label and add any desired custom help text.
  3. Click Save in the top-right corner to apply your changes.
  4. The file upload element is now added to your Smartsheet form, allowing participants to add attachments when they complete the form.

📌 Why this matters

Collecting file attachments directly inside a Smartsheet form eliminates the need for separate email threads or third-party file-sharing tools, keeping all project data centralized in one workspace. The built-in File Upload field lets form respondents attach documents, images, or supporting files at the point of submission, reducing follow-up requests and speeding up workflows. For teams that rely on Smartsheet to manage requests, approvals, or intake processes, adding an attachment field ensures every submission arrives complete with the necessary supporting materials. This feature is especially valuable for HR intake forms, project request forms, and any approval workflow where file evidence or documentation is required.
