There is often a situation where some business logic starts from the spreadsheet (Google, ODS, XLSX). You can enter data to some cells and upon that data, some other cells are calculated. Later often it is required to convert that into a web form. Usually, then the junior dev makes it manually with JS and then the front-end guy implements the design.
I Googled but didn't find it. I just wonder why there isn't already a tool that would provide me with the undesigned HTML and JavaScript for example (could be another language) where all the cells from the spreadsheet that didn't have a formula in it would be input areas and the ones with formula in it will be just uneditable text.
