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 csv/sum.csv
