Hello,

Thanks for your inquiry.
The free version does not require a license, and it is a forever free product for commercial and personal use.
In addition, Free version is limited to 5 sheets per workbook and 200 rows per sheet. This limitation is enforced during reading or writing XLS or PDF files. When converting Excel files to other formats, such as PDF/XPS/Images, you can only get the first 3 pages of PDF/XPS/Images. If your document exceeds the limitation, you can evaluate our commercial version from the following links for the latest version of Spire.Xls. We are willing to provide a temporary license (one month free) to help you remove the warning message. If you need it, you can contact our sales team (sales@e-iceblue.com).

Download links:
1) Spire.Xls 12.8.1 for .Net
2) Spire.Xls 12.8.4 for Java

Sincerely
Abel
