Convenient for use, excellent support team

Our company purchased the licence for GemBox.Document. It’s excellent library for generating documents (docx, pdf and so on). GemBox.Document has сlear manuals, it’s very cool, because it saves a lot of our time. Also support team always can quickly help with the solution of the issue. We are glad to work with this company!

GemBox.Email

I'm using GemBox.Email to monitor IMAP-Mailboxes. The component has all required functionality. The GemBox support is always speedy and helpful.

Excellent features, performance, support and developer experience.

Our project generates very large pdf documents, at times thousands of pages. In the process we need to perform content generation, existing content manipulation, and merging of hundreds of documents.

Most PDF packages did not have a couple crucial features we needed and the ones that did were fairly slow and very memory intensive. Gembox was able to achieve our desired output with a 10-15x speedup and a ~80% smaller memory footprint, in some extreme cases.

From a developer perspective, the design of the library makes sense with nothing being more complicated than it needs to be along with being very easy to reason about.

The support we've received in fielding some fairly edge-case implementation questions has been excellent. Very quick to respond with concrete solutions to solve our problems.

I've worked with a lot of vendors over the years and very rarely have I had such a positive experience.

Gembox Document is a great product that makes document and report writing easy. I've been using it a long time. I especially like how it incorporates record sets right out of the box. Their customer support is also awesome and very responsive and very helpful for novice users.

Stellar Support! Superior software! Lightweight and fast!

Support was stellar! I didn't have much to go on except our business name and our product key. I sent them an email asking for some help and general direction. I spoke with Mario, and he went above and beyond in my opinion.

I am a novice programmer and was able to re-write a visual basic app that was using word.interop using the Gembox in a few sleepless nights. Gembox is by far much faster than word interop!

I would highly recommend checking out Gembox for your document creation needs!

Gembox PDF Is a Great Product

Great Product, we are using it to create manuals for our customers that consist of many different pdf documents from many sources. I am absolutely amazed that I've been able to create pdf documents with 15,000+ pages and 2GB+ in size without issue. Any small issues that have come up have been dealt with overnight by the support team.

Great tool, perfect support

I using GemBox.Document for about 10 years now and I'm very happy with the product. It's very easy to use, performance is good and they are adding new features all the time. But what I appreciate most is the support. It's very fast (reply usually within hours) and professional. So thanks Mario and other developers there for such a nice developer experience.

Excellent Support, professional Tool

I've been using Gembox for about 6 months now and I'm extremely happy with it. On the one hand because the handling is very easy and the result is great, on the other hand because Gembox offers a great support. I have been a software developer for over 25 years and have never experienced such excellent, competent and fast support as offered by Gembox. Many thanks to Mario and his team for the professional help on Word, Excel and PowerPoint I have received so far. I can recommend Gembox software to anyone looking for a robust tool and professional support.

Best in class Support services

Working with Gembox has been a real pleasure. The product is very stable and easy to use, especially for someone with very little dotnet experience.
The support team is best in class in their response times to resolving any issues or questions, with most turned around the same day.
I highly recommend this product to anyone looking to work with Microsoft Office files - you will not be disappointed.

Great tools

Great tools which let us arrange and build Open XML with ease and in a very fast way. What is nice is that the format is not specific meaning that features which are not handled by GemBox are left "as is", so we always keep all features, files are not alterated. The help desk is very responsive, thanks to Mario and Stipo.

Better then Excel

GemBox Spreadsheet is the best product I have seen so far in terms of performance and speed. There is only one product that knows the XLS format better and that is Excel itself, but Excel is significantly slower when it comes to automatic processing of documents.

Good value PDF components! Excellent support!

Our company was looking for a PDF to table conversion and GemBox.Document (along with GemBox.Pdf) turned out to be a very good product.

Although this functionality is considered Beta quality (due to various complexities), still the customer support handles reported issues and provides timely hotfixes.
