Colonial has been a satisfied customer of your Spire.PDF dll library for years; having purchased a license in February of 2015.
We use it in a variety of C# applications, both in website Save-As and automated transformative file creation application situations.

Both Spire.Doc and Spire.XLS are great!
They helped me write a tool that I use in my work for the automated execution of documents. Thank you very much!
I am very happy with these libraries and I will definitely recommend them to my friends.
Best regards, Jacek from Poland.

Spire.Barcode is an excellent product.
It integrates seamlessly and efficiently with visual studio 2017. The documentation makes it very easy to use with the help of examples in most popular programming languages and works well with other software.
The best part is that it works efficiently with my Bluetooth barcode reader. I have tried various vendors but this free one works the best.

Actually Spire.XLS is working fine, it meets my requirements, to save excel as image though C#. Thank you for your product, it helps me a lot in the project.

The library free Spire.XLS meets my expectations completely.
Thanks to the many examples and the very good documentation, the inworking is easy. I am now able to write text and formulas in an Excel worksheet and format the data appealing. I will continue to read from an Excel file.
I'm glad to have found a library so easy to handle for Excel.

Your Tech Support is always excellent. I know a bit about that as I used to run an international development team.
I am always pleased to see people that are careful and professional in the way they deal with customers and help customers to get the best result.
You and your colleagues are very good, so thanks again!

Spire.PDF is definitely the best library for handling PDF I have worked with. Currently I'm only using it to make PDF files from images or other PDF files.
And then your PDF viewer for displaying the files in the program. Which have all been an easy task to implement with the Spire.PDF.

I do like how your Spire.PDF reads the text and keeps the spacing on each line, much better than XXX.

We would like to switch from XXX to Spire.PDF for .NET, the reason for my change is that I find the competitors product not reliable enough.
I did some tests with Free Spire.PDF (with some of my "difficult" files) and am satisfied with your component's reliablility and speed. Also, your object model is very simple and easy to understand.
