Answer 1

You can unzip the zip files in memory in the browser using Javascript.

This answer shows how to do this.

The js code in the browser is as follows:

var doneReading = function(zip){
    DoSomethingWithEntries(zip);
};

var zipFile = new ZipFile(url, doneReading); 

Inside the method DoSomethingWithEntriesthat you provide, you can play with an object representing the extracted zip file.

function DoSomethingWithEntries(zip){ 
  // for each entry in the zip...
  for (var i=0; i<zip.entries.length; i++) {
    var entry = zip.entries[i];
    var entryInfo = "<h4><a>" + entry.name + "</a></h4>\n<div>";  
    // put that into a div, if you like.
    // etc...
  }
}

As shown above, you can emit lists of records with their name, size, date, etc.
