This simple plugin allows you to import any type of data from large CSV files into your wordpress installation.
Plugin reads CSV file and performs import of its records one by one through AJAX requests, so there are no server timeout issues.
You only need to provide PHP function to perform import of CSV field values into post or taxonomy term or whatever you need.
Usage example:
For example, assume we want to import posts from such CSV file: 
 title,text,brand,image 
 “Check this”,”Samsung content”,Samsung,”https://upload.wikimedia.org/wikipedia/commons/thumb/2/24/Samsung_Logo.svg/2000px-Samsung_Logo.svg.png” 
 “Some news”,”News Here are some news”,Philips,”http://www.underconsideration.com/brandnew/archives/philips_2013_logo_detail.png”
Here we have post title, post content, custom field Brand and thumbnail image.
We can use this code in theme’s functions.php file to implement import function:
<pre><code>add_action('lcih_import_csv_row', 'lcih_import_csv_row');
function lcih_import_csv_row($row)
{
 $post_data = array(
 'post_type' => 'post',
 'post_status' => 'publish',
 'post_title' => $row['title'],
 'post_content' => $row['text']
 );
 $post_id = wp_insert_post($post_data);
 if (!$post_id)
 {
 echo "Error inserting post.";
 return;
 }

 update_post_meta($post_id, 'brand', $row['brand']);

 if ($row['image'])
 LargeCSVImportHandlerPlugin::download_post_thumbnail($post_id, $row['image']);

 echo "Created post ".$post_id;
}
</code></pre>
After that we can go to plugin admin page, select CSV file to upload and click “Start import” button. Import process will begin.

Large CSV Import Handler

After trying almost all major CSV plugins, this is the one that works perfectly for large files. I have a file of 35MB with 83000 posts and was unable to import them but this plugin did it with ease. No server time issues, simple to use. Recommended!

Awesome Work, Great Plugin

TablePress – Tables in WordPress made easy


Ich nutze das Plugin nun schon eine ganze Weil und bin immer wieder begeistert, wie einfach man damit Tabellen erstellen und einbetten kann. Dazu kommt, dass der Autor immer wieder neue Funktionen einbaut und das Plugin weiterhin kostenfrei bleibt.



I've been using the plugin for a while now and I'm still amazed at how easy it is to create and embed tables. In addition, the author keeps adding new features while the plugin remains free.






Best Plugin when it comes to tables


Working with TablePress has made it easier to manage data especially when working with hundreds of cells.



No way should one ever work with "plain HTML tables" again! :-)


Intuitive!


Developer solved all my problems, created individual code for my needs and explained everything thoroughly. Great job!


GREAT SUPPORT!!


TablePress 3.0 removed backward compatibility with free extensions. Now you need to use paid version in order for things to work. Someone skilled should fork this. 


Backward compatibility removed in favor of paid version

Embed beautiful, accessible, and interactive tables into your WordPress website’s posts and pages, without having to write code!
