How to import using Export/Import Tool with ocStore 2.3.0.2.3 in Opencart 3.0.2.0?

Question

opencart

Good afternoon. There was a need to import goods from the store on ocStore 2.3.0.2.3 to the store on
Opencart 3.0.2.0.
I do this using the Export / Import module (I installed it separately for ocStore 2.3.0.2.3 and for Opencart 3.0.2.0. I can
export goods to a file with ocStore 2.3.0.2.3, but when I try to load through the same module in Opencart 3.0.2.0 I get an error:
2018-08-31 13:06:04 - Export/Import: Invalid header in the Products worksheet
2018-08-31 13:06:04 - PHP Unknown: The Twig_Autoloader class is deprecated version since 1.21 and will be removed in 2.0.Use Composer instead.in /home/au300858/sitename/www/system/library/template/Twig/Autoloader.php on line 12

What could be the problem?

Answer 1

I would also recommend rechecking the structure of exported files with ocstore 2.3. Make an export with 3 oxstore and compare with oxstore 2.3. There may be discrepancies in the fields or the fields are called differently. I had this when switching from ocstore 2.1 to ocstore 2.3. But I corrected the field headers with pens and everything was imported.

Answer 2

Resave the exported .xlsx file to Excel 2003 (.xls) format. The module on the third opencart for some reason swears at files with a new extension
