Yes, there are several alternatives now to read/write spreadsheets:
a) - using CSV files,
b) - using XML files,
c) - using FPSpreadsheet,
d) - now using ExcelInterface.
Unlike a) and b) ExcelInterface controls Excel directly using the COM
interface, so the interaction with the Excel program is immediate:
formulas can be written and and evaluated automatically by the Excel
solver, the user can input data with Excel filled-in spreadsheets, the
format itself is rendered immediately, moving shapes also move
connectors automatically. It also requires less manual work from the
end-user.
Unlike c) ExcelInterface provides many additional facilities in
addition to the cells and values: formulas, formats, comments, shapes,
diagrams, etc. and works on many Excel versions.
ExcelInterface brings the power of Excel to FPC and Lazarus as a sort
of additional external component.
In the future, I hope to add a similar interface to link to
OpenOffice, so as:
- to have the same interface to generate either OpenOffice or Excel
spreadsheets,
- to be able to run the interface on Linux.
There's http://sourceforge.net/projects/uno-pas-bridge/ . The svn
version is running under Linux and Windows. What's missing is updated
instruction how to install on Linux and Windows since is not straight
