Hello Christophe.

Thank you for your purchase.

Don't apologize for your English - it is quite good.

This format will work only up to a certain limit (no exact limit, but 3000-5000 cells is a good example). If you have a larger file, the page load time will increase. For large data sets it makes sense to import the data to MySQL, you can use “Create a table by importing data from data source” option to do this.

The plugin simply cannot handle that much data if it's not coming straight from the database.

Best regards.

Hi again Christophe.

I believe we don't understand each other here.

You cannot import a file that big through wpDataTables (WordPress), but instead you have to open PHPMyAdmin (your database), and import it straight in the database:

Since this is a CSV file, make sure to check this:

So, the first line of the file become table headers.

Once imported, you can use the first option when creating the table and create it using an SQL query, like this;

SELECT * FROM your_table

Unfortunately, you cannot import multiple files in the same table. Again, you'd be able to do this via PHPMyAdmin, importing another file (with the same contents) to the table you just created.

Best regards.
