Modify a script to import catalog to Prestashop (Categories and Taxes import are now working fine now)

Job ID: 31521785

Budget: €8 – €30 EUR

Modify an import script that worked well on other website but here don’t import categories and taxes.
If this job goes all right we want to create a Prestashop module to execute easily these scripts from Prestashop backoffice.
These scripts was working well on a old hosting and domain, but now, don’t exist the old site and I will put here. Seems works well, but categories and taxes import are not working fine. About categories, perhaps is related with categories ID? And taxes perhaps too. But I have no idea.
See docx file for more details.
Please, don't bid if after read the attached document you're not agree with price. Thank you!
