Hi, Christopher 

You are correct.

Data that has more than few thousand rows can  not be imported in this way directly via the plugin - this is a limitation that is coming from WordPress itself combined with server performance.

But there is a solution.

What you can do is, you can import the file, in form of Excel, CSV, or spreadsheet directly in your database via your database management tool, such as PhPMyAdmin.

Here is an example how you can do it.

When you're importing a CSV file in your database, you need to navigate to the WordPress database, and click on "Import":

Then click on "Choose file" and select your CSV file:

The structure of the file needs to be set so the first row of the file contains column headers. For example, if the table you're creating is supposed to look like this:

The structure of the CSV file should contain "COLUMN1, COLUMN2, COLUMN3" in the first row, like this:

COLUMN1,COLUMN2,COLUMN3
Google,Test,123
Yahoo,Test2,456
Facebook,Test3,789

Then, when you select that file scroll down, and check the "The first line of the file contains the table column names" check-box, so the first line is used for headers of the table; and then click on GO:

You should see a screen similar to this:

In my case, it's "TABLE 114", and you can click on it to open that database table:

To avoid having any issues when using this table in wpDataTable, my advice is to change its name (because it contains a space). So, go to the "Operations" tab:

And under "Table Options" rename that table to what you want it to be. 

Just make sure not to include dots ( . ) or spaces (don't use any special characters). You can rename the table to be "table_1" for example. After you rename it, click on GO in the right corner of "Table options" section:

And that's it. You're now able to create an SQL query based table using this query (for example):

SELECT * FROM table_1

Let me know if you have any questions.Thank you

Hi, Christopher 

Sorry for the delay

The "current" database name is just a name we use for testing purposes, but on your site, as you have correctly checked, it is +desputin_test03.

2. Yes. There is a way , if you split your initial CSV file to lesser "chunks" of data sets,

then you can try to import, for example, a couple of thousand rows first ( maybe up to 5000 rows, depending on how much your WordPress server can handle)  in order to create the new Manual Table through our plugin,  and for it to get created in your WP database;

then you can upload another CSV to add more rows,  and so on.

Please check out this documentation that explains how you can Update manual tables from source files (CSV, Excel or Google sheet).

Let me know if that helps.
