Live products database?

The database can be edited directly in cpanel or your host’s equivalent using phpMyAdmin. However, the product data is in more than one table and one slip in editing the tables could corrupt your data. Not recommended.

For managing many products at once, you can use the built in CSV exporter & importer. Here’s the guide to using that:

Then there is this plugin. A bit easier than the above method. It presents product data as an editable table. However it does not give access to all product fields. So it depends what you want to do.

Also there is Smart Manager. The free version allows only 3 edits at a time but its a good way to try it out before considering the pro version.
