Metafields2

We use metafields extensively in our theme. This app makes it easy and convenient to manage that data. For example, we use metafield data to communicate lead times for out-of-stock products. Other uses might be country of origin, or special handling instructions, or a quote from a happy customer. If you need to go beyond the basics, this app is highly recommended. Been using it since 1.0 very happily.

The Gift A Feast website would not be possible without the Metafields app! We need to be able to detail contents of our gift baskets and introduce customers to our artisan producers and metafields have been the solution.

I tried a few Metafields apps, starting with the cheapest and working my way up...I've now been using this app off and on for a few weeks and, while its output format isn't the best (one row per product per metafield, rather than columns), it's perfectly workable for someone with Excel skills and I find it rather good!
Apart from the bulk export and import facilities (more of that in a minute), the display of information is good and clear. You can select product, collections, whatever else Metafields, to keep things tidy and when you list a single product or collection, or whatever, you're met with a full list of the Metafields applicable to 'whatever you're looking at', along with values. Any or all may be updated on that page, with one 'Save' button. New Metafields may also be entered here (and which then apply to all of that genre -products, collections, etc.). You can also perform a search so you quickly arrive where you want to be.
Simple, intuitive, comprehensive.
The only problem....is that although the app exports a nice csv file, which may be read by Excel and worked on within Excel - the export from Excel (in UTF-8 format, then opened and saved by Notepad in UTF-8 format, to ensure the file *really is* in UTF-8 format, as Excel doesn't do a good job with that) - cannot then be imported back into Metafields2, as there are some 'dodgy' characters hiding there at the beginning of the file.
However...with help from Joe and some experimentation, I've found it's possible to do all the above, working in Excel to do the 'bulk of the job', then open the exported csv file in Google Sheets - and then just save it. This results in a perfectly serviceable, *proper*, UTF-8 file that can be imported back into Metafields2.
Maybe a long winded review, but if it helps anyone with similar problems in the future...I think the app deserves it. It's a good app.

The developers are incredibly helpful and supportive. They went above and beyond to help. This app works well and serves as a bridge for my store's products and their many complicated configurations.

We needed a simple and efficient way to bring in multiple metafields into our complex store - trueclub.com. This is an app that does exactly what it says. Great user interface and great support. We can’t recommend it highly enough.

A surprisingly useful little app. It solved a major problem for us (we couldn't add editable content to a particular page on our site), and this was a really slick solution. Thanks!

Perfect app to allow both retail and wholesale customers on the one store front, and allow for quantity breaks, custom messages and more! Love love love this app!

Very nice app for add custom input to back-end. It would be very nice in the future to support more type not just string and integer. But is very easy to use and well done. Support is great, and they will response to any questions...

Basically, we wouldn't be able to carry the large assortment of personalized products that we do without this app. Straight forward and easy to use once you understand the advantage of utilizing metafields.

This is an awesome app. This app will save lots of time and is already an asset to me in running my site.

PLUS, I received first rate support from Chris who actually walked me through the basics with a Skype screen share. Great app + steller support = :-)

If you have detailed product descriptions or info/specifications that apply to sub groups or only certain items, this is perfect for updating your site quickly via the CSV upload for newly created fields.
