We are currently making a major overhaul to an old website of ours, and it is still using Magento Version 18.104.22.168. I know it is very outdated.
We have a lot of orders here that we want to make a backup of, such as name, email address, telephone order, sale amount, date of order(s), items ordered, etc.
There are over 10k transactions.
How do I easily back it up in a reader friendly format, preferably on a spreadsheet?
I have seen plugins like https://marketplace.magento.com/raveinfosys-raveinfosys-orderexporter.html but it only goes until version 1.5.
I have a little programming knowledge, but prefer an easy way to do it.
