Good Tables is a free tool that helps you find out if your tabular data is actually good to use. It can check for structural problems, like blank rows and columns, as well as ensuring that your data fits a specific schema.
The tool is particularly useful for journalists working with open data. Often, these datasets are available in CSV and Excel formats, which leave them vulnerable to containing bad data.
By simply inputting these data into the Good Tables interface, the tool is able to detect errors and fix them in the source.
