Allow respondents to attach multiple files in a survey

Researchers from all fields, including marketing, healthcare, communications, education, government, non-profit organizations, human resources, etc. use online surveys for data collection. An advanced survey maker is designed to support simple, as well as the complex needs of the researchers. Keeping up with the trend, many online survey platforms introduced the file upload question in the past. It helped open up a whole new world of potential uses. 

For example: If respondents want to upload a photo, they can simply upload the photos by clicking the button or by dragging and dropping the selected photos in question. Respondents can use smartphones, tablets, laptop or desktop to upload the files. 

About upload file question in the survey 

Whether it is a customer feedback survey, employee engagement survey, or campus evaluation survey, the file upload question helped in increasing responsiveness and collecting quality data through a survey. As we say “every good change comes with limitations”, file upload question had its limitations too. Yet, not every online survey software thought of overcoming these limitations.  

We at QuestionPro are committed to evolving with your needs. Hence, we came up with a major update in the file upload question. The scalable feature apart from its robust platform and core set of features will now allow respondents to upload or attach multiple files in response to the single question. 

What did we change? 

Previously, the file upload question used to have limited functionality. In response to the file upload question, survey respondents were able to attach or upload only one file, that too of specific capacity.

  • Support for multiple file types: Now respondents can upload multiple files from their desktops or mobile devices. In addition to that, the surveyor can easily download all the uploaded images via an analytics panel. It does not matter whether respondents want to attach a video, audio, image or a text file, the revamped file upload question is designed to support all the possible file types. 
  • Set upload limit: Now, users can set a specific upload limit depending on their needs. By setting the upload limit you restrict respondents to upload the files up to a certain limit. 
  • Select the number of files: Now users can decide how many files they want to receive in response to a question. Accordingly, they can set the file upload limit by going to the question settings. Users can set any number from ‘1’ to ‘10’ as per the motive of their survey.
