The File Upload question type allows respondents to upload a file along with their survey response. Using File Upload, you can collect data that may not be available through standard survey questions.
You can have as many File Upload questions in your survey as you would like, however each question can accept only one uploaded file. Files uploaded need to be smaller than 16MB. For security reasons, executable files (such as those ending in .exe) are not permitted.
File Upload Options
File Upload questions are fairly straightforward, with one main adjustable option. You can restrict the type of file respondents upload. For example, if you are asking for a photo, you may want to restrict respondents from uploading spreadsheets.
To set this requirement, select Content Validation in the question Editing Pane and choose the appropriate Content Type.
Content options are PDF, Document (DOC, DOCX, TXT, ODT), Spreadsheet (CSV, XLS, XLSX, ODS), or Graphic (JPG, PNG, GIF). You can also choose Extensions and type in your own custom allowed file extensions. Custom file extensions should not include the period before the file name and need to be separated by a space or a comma.
File Upload Logic
When utilizing the File Upload question, you can use special logic conditions in Display Logic, Skip Logic, Branch Logic, Custom Validation, and other areas. You can add logic based on the following:
- File: Base logic on whether a file was uploaded or not.
- File Size: Base logic on the number of bytes the uploaded file contains.
- File Type: Base logic on the type of file that was uploaded (PDF, Document, Spreadsheet, Graphic, Custom Extensions).
Once your responses have been collected, Qualtrics offers various methods to create reports both in and out of the platform. From the Results module, you can view aggregate data with pre-made reports as well as create your own. From the Responses module, you can view and manipulate your survey responses on an individual basis.
There are two visualization types available for File Upload questions: Paginated Table and Word Cloud. For more information on these visualizations please visit the linked visualization support pages.
Note that File Upload questions display slightly differently than their cousins the text entry question when viewed in a Paginated Table. With the File Upload question, you will be able to see an uploaded file’s name, and also be able to click on the name to view the actual file in your browser. In a Text Entry you can only see the text entry text, there will be no link to extra content.
Downloaded Data Format
Rather than downloading your uploaded files in spreadsheet form, you can download a ZIP file with all the files uploaded by your respondents. When exporting your data in Responses, just choose the User Submitted Files format.
