Export Database table to CSV file
Sometimes you want to export some database tables to a CSV file for analysis or backup.
I have developed an extension for Joomla called "Table to CSV". It will list all the tables of the current database.
If you want to export any table, just click the "Export" button and wait for the download:

For large tables, it will show the progress so you can easily observe. This extension is suitable for Joomla 3, 4, 5 and 6.
InPre-Update Check for Joomla 5.4.4
for Off-Canvas it says
Joomla cannot detect the extension's compatibility with the target version of Joomla.
have you implemented the compatibility stuff for Joomla to upgrade extensions correctly ?
Have got two off canvas menus working (1. for tools and 2. for main menu)
However I can only get the Main menu to display the first level of menu items.
Have you any suggestions for getting the sub menu items to display ?
N.B. the menu item with sub menu items does display a down arrow, but trying to click on it only display the item at the main menu level.

If you want to see where I have currently got to
What is wrong?
That imported page keeps on saying this, but nothing further is happening...
1. The "radio buttons" extra field doesn't transfer the values in the additional field, e.g., "yes" or "no," and only enters certain values into the #__fields_values database.
2. The "textarea" extra field with the "Use editor" option checked converts to "textarea" when it should be "editor."
3. In K2, the extra field group is assigned in the category. In Joomla Articles, the category is assigned in the extra field. It would be nice if this were automatically completed. A checkbox could be added if someone doesn't want this option.
