Documonster, a modern ExcelJS based alternative

First of all, a big thank you to the ExcelJS author and all contributors. ExcelJS has been a great project and has helped many developers for years.

We are building Documonster, a multi module document processing library derived from ExcelJS, previously known as ExcelTS.

We are now moving towards a stable 1.0 release and would love to invite the community to give it a try.

Key features:

• Zero dependencies
• One API across multiple platforms
• Full ESM + CJS support
• MCP support
• Convert between multiple document formats

Beyond Excel, Documonster also provides modules for ZIP, Word, PDF, Markdown and more, with a common API and format conversion capabilities.

With AI assisted migration, existing ExcelJS projects can often be migrated to Documonster in around an hour.

Feel free to try any of the modules. If you run into any issues, please let me know and I will do my best to fix them.

Feedback are very welcome!
