  Is there any way I can limit how many characters the user can input to a single cell?

  The example you refer to is for SpreadJs.sheet, how do I use it in spread.views?

  In case of Spread.Views we could handle the editing event and then set the max-length attribute on the input element.
  
  Please refer to the following code snippet and attached sample:

  dataView.editing.addHandler(function(s,e){
              // apply max length
              if(e.status == "startEditing"){
                  var editorContainer = s.container.querySelector('.gc-inline-editor-container[data-column="country"]');
                  if(!editorContainer){
                      return;
                  }
                  let inp = editorContainer.querySelector('input');
                  if(!inp){
                      return;
                  }
                  inp.setAttribute('maxlength', '8');
              }
              
              // forcing country check
              if(e.status == "beforeEndEditing"){
                  if(e.newItem && e.oldItem && e.oldItem.country != e.newItem.country){
                      // country changed, check length
                      if(e.newItem.country.length > 8){
                          // force validation, restore country or trim input
                          e.newItem.country = e.oldItem.country;
                      }
                  }
              }
          });
