What's this?

sowhat converts an image file into an excel file.

Input image:

Output (Excel file):

Each cell represents a pixel of the image.

Usage

1. clone this repository and bundle install.
2. bundle exec ruby sowhat path/to/image_file
3. you should see an excel file in tmp dir

This may take a few minutes (or even hours. It depends on the image size and machine spec) to finish. I recommend you try this with a tiny image like 30 * 30 for the first time.
