How to preprocess file before Feeds upload I am using Feeds 7.x-2.0-beta1 .  I am getting the data in a format that I need to change before inputting, since they are adding one item per row when some data has multiple values in one field . I want to modify the file to put all of those values in one field and one row before continuing with the feeds parser.
Where can I put the php code to do this? what hooks are available? thanks
The Feeds project page doesn't advertise it, but there is an API. If you look at feeds.api.php you can view all the hooks it makes available. A few of them take action before a feed item is processed or saved.
