How to check the value from data sheet during Feeds import?
Thanks everyone, I got the answer. Instead of using Rules, I created a "custom feeds module."

Steps:


Create a folder named "custom_feeds"
Create two files, one is "custom_feeds.info", another is "custom_feeds.module"
Add following information in the .info file:


name = custom feeds module
description =custom feeds module
core = 7.x
package = Feeds
dependencies[] = feeds&lt;/code&gt;



Add following code in the .module file inside &lt;?php ?&gt;:


function custom_feeds_feeds_presave(FeedsSource $source, $entity, $item) {
  // check that this is fired only for the importer being used
  if($source-&gt;importer-&gt;id=='recommended_product_import'){
     // "equivalent" is the column name in excel sheet
     if(!strcmp($item['equivalent'],"")){
       $entity-&gt;feeds_item-&gt;skip = TRUE;
     }
  }
}
