What's the paper from SharePoint Document Library?

[kalena]

Hello, this is a big deal. The document Excel.xlsx should be added to SharePoint Document Library, then ferryed and placed on the List. I can't understand the password process, if only some cells are needed, how do you make a sample of them?

Thought to use the SpreadsheetLight Library. Who would have thoughts about the task?

And it's not gonna work with Interop-op because there's no Aphis on the server.

This is a good example of how to do this with Ajax(JQuery)

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
    $("#upload").bind("click", function () {
        var regex = /^([a-zA-Z0-9\s_\\.\-:])+(.csv|.txt)$/;
        if (regex.test($("#fileUpload").val().toLowerCase())) {
            if (typeof (FileReader) != "undefined") {
                var reader = new FileReader();
                reader.onload = function (e) {
                    var table = $("<table />");
                    var rows = e.target.result.split("\n");
                    for (var i = 0; i < rows.length; i++) {
                        var row = $("<tr />");
                        var cells = rows[i].split(",");
                        for (var j = 0; j < cells.length; j++) {
                            var cell = $("<td />");
                            cell.html(cells[j]);
                            row.append(cell);
                        }
                        table.append(row);
                    }
                    $("#dvCSV").html('');
                    $("#dvCSV").append(table);
                }
                reader.readAsText($("#fileUpload")[0].files[0]);
            } else {
                alert("This browser does not support HTML5.");
            }
        } else {
            alert("Please upload a valid CSV file.");
        }
    });
});
</script>

<input type="file" id="fileUpload" />
<input type="button" id="upload" value="Upload" />
<hr />
<div id="dvCSV">
</div>

Result:
