The XLSX plugin allows you to conveniently read and write XLSX documents from
Hollywood scripts. It offers a wide variety of functions to set and get cell
values, cell types, cell formulas, document/worksheet properties and several
other attributes. It also offers an iterator function for a high performance
iteration of a large number of cells.

On top of that, the XLSX plugin also supports Hollywood's serialization
interface which means that you can conveniently serialize Hollywood tables to XLSX documents by just a single call to Hollywood's SerializeTable() function.
In the same manner you can also deserialize whole XLSX documents into Hollywood tables by a single call to Hollywood's DeserializeTable() function. It just

doesn't get any easier!

Builds of this plugin for other platforms (Microsoft Windows, macOS, Linux...) are available from the official Hollywood portal which you can find

Does Hollywood support AROS x86-64 or only x86 ?

only x86

Programs written for x86 (e.g., using Hollywood) run on x86_64 in emulation mode, but the emulator does not support networking.
