Minicel
The idea is to implement a batch program that can accept a CSV file that looks like this:
A | B
1 | 2
3 | 4
=A1+B1 | =A2+B2
And outputs:
A | B
1 | 2
3 | 4
3 | 7
Basically a simple Excel engine without any UI.
Quick Start
The project is using nobuild build system.
$ cc -o nobuild nobuild.c
$ ./nobuild
$ ./minicel input.csv
