CSV to jQuery tablesorter

Display any CSV file as a searchable, filterable, pretty HTML table. Done in 100% JavaScript.

This project is alternative to derekeder/csv-to-html-table with substitutions:

Check out the working demo: https://pavelsr.github.io/csv-to-tablesorter/

In demo <thead> is predefined in html code but you can easily read it from csv file or add dynamically with js.

You can also rewrite createTable() function according your needs - e.g. for pretty output of links, images etc.

By default all dependencies are loaded from cdnjs.cloudflare.com

HOW TO

Define thead is javascript

You can redefine createTable() like that:

function createTable(tableData, callback) {
    var table = $('table#jquery-table');
    
    table.empty();

    table.append(
        $('<thead>').append(
            $('<tr>').append(
                $('<th>').text("Col1 header"),
                $('<th>').text("Col2 header"),
                $('<th>').text("Col3 header"),
                ...
            )
        )
    );

    var tbody = $('<tbody>');
    $.each(tableData, function(x, row) {
        var tr = $('<tr>');
        $.each(row, function(y, col) {
            tr.append( $('<td>').text(col) );
        });
        tbody.append(tr);
    });

    table.append(tbody);
    
    callback();
}

or make thead more elegant:

var header_columns = ["Header_1", "Header_2", "Header_3"];
var thead_tr = $('<tr>');
$.each(header_columns, function(x, hcol) {
    $('<td>').text(hcol).appendTo(thead_tr);
});
table.append( $('<thead>').append(thead_tr) );

Get header from first row

You can set PapaParse header option to true and pass to createTable() results.meta.fields in addition to results.data (or just pass whole results object)

var table = $('table#jquery-table');
var thead_tr = $('<tr>');
$.each(results.meta.fields, function(x, col_h) {
    $('<td>').text(col_h).appendTo(thead_tr);
});
table.append( $('<thead>').append(thead_tr) );	

Change columns order other than it's defined in parsed CSV file

After particular

Hide columns from result table

You should excluse field from thead and tbody both:

$.each(results.meta.fields, function(x, col_name) {
	if ( col_name == "Col_name_to_exclude" ) {
		return true;
	}
    $('<td>').text(col_name).appendTo(thead_tr);
...
$.each(results.data, function(x, row) {
    var tr = $('<tr>');
    $.each(row, function(col_name, col_value) {
        if ( col_name == "Col_name_to_exclude" ) { // не отображаем вообще
			return true;
		}
        tr.append( $('<td>').text(col_value) );

Create table in case if tableData is array of objects instead of array of arrays

E.g. if you are reading data from JSON API following code example can be useful

$.each(tableData, function(i, item) {
    $('<tr>').append(
        $('<td>').text(item.prop1),
        $('<td>').text( js_func_1( item.prop1, item.prop2 ) ),
        $('<td>').append( '<a href="' + item.prop3 + '" target="_blank">'+ js_func_2(item.prop4) + '</a>' ),
        ...
    ).appendTo( table.append( $('<tbody>') ) );
});

Allow header word transfer

It's done automatically

Get file change date

You can do it with jquery

$.get( csv_filename, function( data, textStatus, request ) {
	$("span#file_date").text( request.getResponseHeader("Last-Modified") );
	Papa.parse(data, { ...

Dynamically add columns

You should add headers at Papa.parse complete callback, at results.meta.fields array. Otherwise it will not tied properly

Papa.parse(data, {
		complete: function(results) {
			results.meta.fields.push('New column header');

An you should fill dynamic columns values at createTable() row iterator

Data formatting for filtering

Most good option is formatter widget - it allows to save original cell text within the table cell data-attribute to maintain the sort order.

widgetOptions: {
	formatter_column: {
        1 : function( text, data ) {
			console.log( "text in cell: " + text);
			console.log( "text in 2nd column: " + $(data.$cells[2]).text() );
			return _func( text, $(data.$cells[2]).text() );
		}
    },
    ...

Papa.parse parse all as string by default ( if you haven't set dynamicTyping: true )

You can use this construction for rounding numbers

parseFloat( str.toString().replace(",", ".") ).toFixed(2)

Host data as JSON API on Github

Possible console errors

XML Parsing Error: not well-formed

In console you can see that error.

There is no problem if you see it locally and other code is working fine.

This error appears only because csv file has no Content-type: text/csv headers, inserted by server.

If you still annoyed by this you can run

python -m SimpleHTTPServer

and check your code on http://localhost:8000/

TypeError: e is undefined on jquery.tablesorter.widgets

It's a problem related to select2 widget

Possible reason is empty field that's needed to be filtered ( e.g. it could be caused of trailing newline in end of csv file )

You can remove trailing newline in end of file with perl -pi -e 'chomp if eof' demo.csv

For exact debug please inspect array after Parsing complete message.

UPD: More elegant solution: set skipEmptyLines: true at Papa.parse().
