4.5/5
What do you like best about OneSchema?

- OneSchema makes it easy to create custom importers that are intuitive, customizable, and polished

- The team reliably provides quick support for any questions I might have about the product, and will provide enterprise-grade responses no matter how niche my question seems Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

- I would like enhanced customization options for the importer, though the current version is great

- Some consolidation/better UX around data transformations would go a long way in speeding up the development process Review collected by and hosted on G2.com.

"Very intuitive developer experience and stellar UI for users."
4.5/5
What do you like best about OneSchema?

The UI is intuitive and fast for users. Also the configuration for setting it up in a products is easy and consistent. They give the team / business using OneSchema a lot of different options and as we have been using the product, the options keep increasing as well. This makes it very nice to work with and lets our companies systems take over when needed, while still using the beautiful UI that OneSchema provides. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

OneSchema can be difficult to integrate for a company that doesn't already have established practices with Functions technologies, such as AWS lambda or Azure Functions. But if your company does, then it should be a breeze to integrate OneSchema into your product. Review collected by and hosted on G2.com.

"Excellent CSV importer- Easily the best on the market!"
5/5
What do you like best about OneSchema?

The ease of use for non tech savvy users! It is very easy to embed within your own software and has saved thousands of hours of work. Solving data issues for my company and clients was my top priority and Oneschema has all the answers. I love how they are constantly rolling out new features. Their new SFTP/API feature looks like its going to be amazing for what we do. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

I can't think of any downsides or dislikes. If it was compatible with LWC components/salesforce that would be amazing but I think that is a salesforce limitation not Oneschema. Review collected by and hosted on G2.com.

"Great demo on One Schema"
5/5
What do you like best about OneSchema?

OneSchema definitely seems like the way of the future when it comes to importing data. It is user friendly and the way it highlights errors for data ingestion correction is extremely useful. Our current import process is not user friendly, old and clunky. I would like for all projects here at Huron to start using OneSchema. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

Going through the security process of utilizing OneSchema seems to be a hassle. I am not sure if there is a way around this but it would be nice to not have to go through so many loops. Review collected by and hosted on G2.com.

"Awesome, very helpful tool, intuitive and makes the data process quick and easy"
5/5
What do you like best about OneSchema?

The way that it learns as you use it, also remembers a lot of changes you have made so it's not repetitive and troublesome to use. My complete time has decreased since I've started using it. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

Sometimes the small screen is annoying with all the messages telling you that there is an error so you have to go back and open the complete view. I would also love if the tool could be even more intuitive as it is now. Review collected by and hosted on G2.com.

"Excellent Validation Tool and Great Team to Work With"
4.5/5
What do you like best about OneSchema?

As a developer my favorite part about OneSchema is how responsive they are to inquiries I have and how accommodating they can be with requests from our team. We feel heard and our needs are addressed quickly. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

The only slight downside I've experienced is that the use of the embedded portal can sometimes feel a little limiting in that we don't have full control over it. But this is to be expected as it is a standard embedder they provide. Review collected by and hosted on G2.com.

"Huge cost savings and much improved import experience for our customers"
4.5/5
What do you like best about OneSchema?

Oneschema has made it easier for our customers to map columns and clean up data, which results in more successful imports and more users getting activated with our product. Implementing Oneschema was much more convenient and faster than developing a custom Importer from scratch, resulting in significant engineering time and cost savings. It's also great to see the team is pushing out a lot of new features and improvements to the product. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

During the trial period, the implementation of Oneschema into our product felt a bit rushed. We were initially given a two-week trial, and we were pressured into making a purchasing decision prematurely. We were eventually given more time to properly evaluate the product, but it required some push back from our team. We were also hoping a couple of key features would be available such as a built-in Google Sheets picker and a custom settings screen. Review collected by and hosted on G2.com.

"OneSchema is a lean, focused, and clever data import tool"
5/5
What do you like best about OneSchema?

OneSchema earnestly researched the pain points that we have when importing from the messy lands of real world data. You can tell they are driven by solving the problems customers actually face, and they continue to steadily improve the platform without breaking things. The interface is intuitive and clean, and easy to jump into. The features you need are usually right where you reach for them. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

There is nothing we dislike so far. We haven't run into a problem for which we didn't get a satisfactory response. I just hope they don't get bought by a big soul-less holding company. Review collected by and hosted on G2.com.

"OneSchema is a great tool for data processing"
5/5
What do you like best about OneSchema?

I love how easy it makes it to add validation constraints and QA data before uploading it into our database. Their validation and importer webhooks are great too! Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

I guess the error list can be a bit clogged sometimes. But I feel like that is a hard UI solution to come up with, so the way it is now is perfectly functional. Review collected by and hosted on G2.com.

"Great tool for your data - OneSchema"
4.5/5
What do you like best about OneSchema?

It is easy to use, integrate, customize and implement in a variety of workflows. The user experience is very easy to understand and convenient to use. The solution is highly scalable, reliable and capable for most enterprise-level uses. Review collected by and hosted on G2.com.

What do you dislike about OneSchema?

The price is quite expensive on the low end. Even for a relatively early-stage company when we first started using OneSchema it was very expensive. A more scalable pricing structure will help attract even more smaller/earlier stage businesses. Review collected by and hosted on G2.com.
