 # SmartCSV.fx
-##Description
-A simple JavaFX application to load, save and edit a CSV file and provide a JSON configuration for columns to check the values in the columns.

+## Description
+A simple JavaFX application to load, save and edit a CSV file and provide a [JSON Table Schema](http://specs.frictionlessdata.io/json-table-schema/) for columns to check the values in the columns.
 
-##Motivation
+## Motivation
 At work I have the need to fix wrong CSV files from customers. It is hard to find the errors and fix them in a texteditor, 
 even in a "normal" CSV editor. So I decided to write this simple JavaFX application.
