Magento Product Export Not Working - getting "No Valid Data Sent" error

Are mysteriously corrupt records causing your exports to fail?

Sometimes Magento Community Edition version (and perhaps other versions) throw an error when you try to use the built-in product export feature. I've been able to find the particular product SKU's in my catalog that are causing the export routine to bomb, but I couldn't for the life of me figure out what was wrong with these records. I could not trace a specific condition back to the problematic records for something to blame, such as simple versus complex product types, attribute sets, funky characters or encoding, missing values - nothing. It seemed as if there was some sort of invisible problem with certain records that would cause the product export to fail.

I looked in the exception log and saw this super-helpful error message:


Magento Complex Product Types Cheat Sheet - What the FUDGE?!?

Mostly from Magento Connect:

Complex Products

Complex products in Magento are a way to consolidate product variants onto a single product info page in the front-end. The variants themselves are actually simple products and have their own SKUs and stock management. This is very powerful - it allows you to let customers search for the individual variants, but browse only to the consolidated product pages.


A Bundle is a “build your own” product type
Bundle Items can be Simple or Virtual products, but without Custom Variants and Options
The Price View of a Bundle can be set to display a price range or “As Low as”
The SKU and Weight of a Bundle product can be set to either “Fixed” or “Dynamic”
Items can have either a preset or user-defined quantity
Items can be shipped together or separately
Bundle product data cannot be imported into your catalog.
