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