Fullscreen CSV Viewer In JavaScript – Heiho

Description:

Heiho is a Vanilla JavaScript based CSV Viewer used to present your CSV data in a spreadsheet-like data grid.

How to use it:

1. Add the Heiho’s JavaScript and CSS files to the page.

<link rel="stylesheet" href="heiho.css" />
<script src="heiho.js"></script>

2. Populate the online spreadsheet with CSV data you provide.

var data = [ CSV Data Here ];
Heiho(data);

3. Or directly load an external CSV file into the CSV viewer. Requires the PapaParse library.

<script src="https://cdn.jsdelivr.net/gh/mholt/[email protected]/papaparse.min.js"></script>
Papa.parse('sample.csv', {
  download: true, 
  complete: function(results){ 
    Heiho(results.data) 
  }}
);

4. Determine whether to style the first row. Default: null.

Heiho(data, {
  header: null
});

5. Customize the title of the CSV viewer.

Heiho(data, {
  title: 'sample.csv'
});
// or
var file = {filename: 'sample.csv', size: '10KB', created: '2020-09-28 13:06:36'}
Heiho(data, { title: function(el, o)
  {
    el.innerHTML = '<b>'
      + file.filename + '<\/b> <code>'
      + file.size + '<\/code> '
      + file.created;
  }
});

6. Determine the maximum number of rows to preview. Default: 100.

Heiho(data, {
  max: 50
});

7. Determine how to truncate the content if the rows reach the max.

Heiho(data, {
  truncate: function(el, max, data, o){
    el.innerHTML = 'Showing only first ' + max + ' rows';
    el.style.display = '';
  }
});
