Publish your Excel files and stay in control
You decide if the customer will be able to use the file, for how long, see what he typed, change values in the cells and everything remotely through a dedicated website.
A completely normal excel file. We will wrap it up and give it back to you. You decide which sheets your clients will look at. Which cells will be locked.
You get a URL that you send to your customers. The site is secure and allows them to download the files.
