Still chasing missing email attachments and documents without reference numbers? A Google Forms file upload form collects PDFs, images and other supporting files together with the details needed to review them. Add a File upload question, choose accepted file types and limits, share the responder link and access submissions in Google Drive. A linked Google Sheet can track each request without coding.
Check the sign-in rule first: respondents must use a Google Account to upload files. A form with a file-upload question is not an anonymous document drop. If your audience cannot sign in, use another approved file-collection method. Google documents this restriction.
How to create a Google Forms file upload form: quick answer
To collect files with Google Forms, open a form, add a question, select File upload, set allowed file types and upload limits, then publish and share the responder link. Uploaded files are stored in the form owner’s Google Drive; link responses to Google Sheets to organize document reviews. Respondents must sign in to a Google Account to upload files. Follow the detailed steps below for a complete vendor-document example.
What you will build: a vendor document intake
Imagine a small team collecting purchase orders and signed agreements. Email attachments arrive without reference numbers, leaving a reviewer unsure which contract belongs to which request. This example connects each attachment to a vendor, a reference and a manual review decision. It deliberately avoids sensitive identification documents.
| Form question | Question type | Required | Example |
|---|---|---|---|
| Vendor name | Short answer | Yes | Northbank Supplies |
| Request reference | Short answer | Yes | VND-042 |
| Document type | Dropdown | Yes | Signed agreement |
| Attach your document | File upload | Yes | Signed agreement PDF |
| Reviewer notes | Paragraph | No | Please check the contract date |
Copy this description into Google Forms: Submit one document per request. Add the vendor name and reference. Use an accepted format. Avoid passwords and unrelated personal information. Submission does not mean the document is approved. All names, references and review entries shown here are fictional.
Step 1: Set up the Google Forms file upload question
- Open Google Forms, choose a blank form and enter Vendor Document Intake as the title.
- Add Vendor name and Request reference as required short-answer fields. Create a Document type dropdown with Signed agreement, Purchase order, Delivery evidence and Other.
- Select Add question → File upload. Read the notice and click Continue if Google prompts you.
- Choose allowed file types and set the maximum number of files and maximum file size. For this example, choose only formats your reviewers can open.
- Mark the file upload required and add an optional paragraph field for Reviewer notes.
Use the current limits shown in your form instead of copying an assumed maximum. Google documents file type, file count, per-file size and overall collection settings in its Forms attachment instructions. Consider the form owner’s available Drive storage when setting limits.
Step 2: Decide who may submit and who owns the files
There are two different access decisions: who can open the form and who can inspect its attachments. Workspace administrators may restrict external sharing. A Google Account is necessary for uploading, but it does not guarantee that an outside vendor has permission to use your particular form.
| Intake situation | Use this setup? | What to arrange |
|---|---|---|
| Employees with Google Accounts | Usually | Restrict responders and identify an owner |
| External vendors with Google Accounts | Only if sharing policy permits | Explain sign-in and check external access |
| People without a Google Account | No | Choose another approved upload method |
| Files required in a shared drive immediately | Not directly | Agree a supported filing and ownership process |
Uploaded files are copied into the form owner’s My Drive. Google also says Forms file uploads are not supported when the form is held in a shared drive; respondents cannot upload directly from a shared drive. These are separate restrictions, covered in Google’s shared-drive guidance.
Step 3: Publish and share the responder link
- Open Settings and review the permitted audience and response options.
- Select Publish. Use Manage or Share to set the responders allowed to use the form.
- Copy the responder link, not the form editor link.
- In the invitation, state the sign-in requirement, accepted file formats, file limit and request-reference format.
- Use an eligible account to open the responder link and confirm the recipient can see the intended questions.
A file-upload form cannot be embedded directly inside an email. Send its link instead. The current Google Forms publishing guide explains the responder-link controls and sharing choices.
Step 4: Locate submitted files in Drive
Open the form’s Responses tab. Use Summary to inspect submissions and View folder to locate the files in Drive. Use Individual to open an attachment from a specific response. Google organizes uploaded files under a form folder, with subfolders associated with upload questions.
Preserve the request reference when reviewing an attachment. If a supplier replaces an agreement, distinguish the new submission from the earlier version. Do not assume sharing the response spreadsheet automatically grants every reviewer access to all Drive attachments. Review those permissions separately.
Step 5: Connect Google Sheets and add a manual review queue
To connect Google Forms to Google Sheets, open Responses, choose the spreadsheet destination and create or select a suitable Sheet. The linked spreadsheet can hold form answers, while the uploaded documents remain Drive files. See Google’s response destination instructions.
Keep the raw response tab unchanged. Add a separate Review Queue tab to record ownership and outcomes. Match entries using the request reference and the actual response or attachment link; do not depend entirely on row numbers.
| Reference | Document | Owner | Review status | Next action |
|---|---|---|---|---|
| VND-042 | Signed agreement | Morgan | Needs clarification | Confirm contract start date |
| VND-043 | Purchase order | Alex | New | Match purchase reference |
| VND-044 | Delivery evidence | Morgan | Approved | File approved evidence |
Create a Status dropdown with New, Under review, Needs clarification, Approved and Closed. Assign a person responsible for each request. Submitting a form does not approve a contract, verify an attachment, set a deadline or automatically notify an assignee.
Copy-ready five-step reviewer procedure
- Match: connect the reference number in the form response to the attached document.
- Inspect: open the file and compare its contents against the expected document.
- Decide: record an evidence-based status, decision owner and short reason.
- Clarify: request a corrected submission if needed, retaining the original reference for traceability.
- Close: retain the approved file according to the organization’s access and retention rules.
For broader intake management involving task ownership and follow-ups, read the separate Google Forms request tracker guide. It covers a different search intent and does not replace document review.
Troubleshoot file-upload and sharing problems
| Problem | Likely cause | Practical fix |
|---|---|---|
| Upload requires sign-in | Google Account required | Inform respondents; choose a different approved service for anonymous submissions |
| File rejected | File type, number or size exceeds limits | Check File upload settings and instructions |
| External vendor cannot respond | Form sharing or organization restrictions | Review responder access with the owner |
| Reviewer can see the Sheet but not the file | Permissions are not identical | Grant narrow access to the relevant Drive file |
| Upload unavailable in shared-drive form | Unsupported form location | Use an eligible My Drive form or alternate intake process |
Google’s upload troubleshooting documentation confirms sign-in and file restrictions. Avoid making files publicly accessible just to work around a reviewer’s permission issue.
Why is Google Forms file upload greyed out?
If File upload is unavailable, first check whether the form is in a shared drive: Google does not support file-upload questions in forms stored there. Workspace account or administrator restrictions may also affect which options are available. Use a form owned in an eligible My Drive location or ask your administrator about the permitted setup; do not loosen file-sharing permissions as a workaround.
Keep document permissions and retention under control
Name a form owner and backup, define who reviews files, and decide how long original submissions should remain in Drive. Store final approved documents in the location authorized by your team. Do not request unnecessary personal information, and avoid using an informal form for regulated or highly sensitive documents without an approved policy.
Forms, linked Sheets and uploaded Drive files are separate assets. Deleting a response or spreadsheet is not a substitute for reviewing the related files and records under your retention process. Google notes that form responses can be deleted irreversibly and that the response spreadsheet is a separate file.
FAQ: Google Forms file uploads
Can you use Google Forms file upload without signing in?
No. Google Forms file upload without signing in is not supported. Respondents must sign in to a Google Account even if the form link is widely shared. You cannot turn off this sign-in requirement for the File upload question; choose a different approved intake method if respondents cannot use Google accounts.
Can respondents upload more than one file?
Yes, if the form owner configures the upload question for multiple files. The configured type, count and size rules still apply.
Are uploaded files stored in the spreadsheet?
No. The linked Sheet holds responses and links. Google Drive stores the uploaded files.
Will submitted files be reviewed automatically?
No. This no-code approach supplies a submission record and a manual review queue. Approval authority and escalation rules remain a separate human process.
Your next step
Build the five-question vendor form, add the Review Queue and define who will assess each document. Confirm the sign-in requirement and Drive access before circulating the link. For related projects, browse the Digital DIY guide hub or our separate QR code check-in tutorial.
