Not only is the functionality extremely extensive and totally suited to our various needs, whenever we have a special requirement Data Export Support is always there to help. Their response is very fast and their resolutions to our challenges are in-depth and creative. I cannot recommend them more highly. Updated 5th March:
Complex report required was designed and implement by Jim within minutes of asking. Another valuable addition to the outputs that can be achieved by Data Export, with their usual expert help. Cannot recommend highly enough

Powerful. Totally customizable. Indispensable. And support is always incredibly efficient, friendly, and effective. Can't imagine using Shopify without this essential add-on.

They did an awesome job of copying my report over from another store. We use them on several of our stores!

Absolutely the best app and the best support i ever encountered.
I can only recommend this guys. I needed something and the support reacted instantly (in 3 mins).

All the team have been a great help in getting us set up with the Custom Reports we needed. So far the app is providing everything I need.

We like to track revenue by "collection" in order to get a better sense of profitability, and we input this data (and fee data) into our accounting system. We use Data Export to give us a daily breakdown of revenue by "collection" with fees. When the deposit comes through from Shopify, everything is appropriately categorized and can reconciled.

This app had the reporting aspects that I was looking for. Right from the start, a "contact" box is available should you need any help. Their support was extremely receptive, addressed the question within a minute, and modified the report for me based on my requests. First impression was great!

This app worked perfectly for my needs. The support team responded quickly to help me gather the data I was looking for. I would recommend this app to anyone looking for more advanced reporting.

Desperately needed a report for sales by location which I thought would be achievable from within Shopify reports but alas it wasn't! So checked out a few Apps that do extra reporting and chose Data Export. Sent a message for some support and hey presto got my location report set up. Cheers
