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.

Our team was in need of a .NET utility that would allow us to generate barcode images used for emailing receipts.
Spire.Barcode not only provided the ability to generate barcodes and save them as images, but offers a range of customization that suited our needs perfectly.
The fact that these services are completely free is almost too good to be true!
