Good Tables is a free online service that helps you find out if your tabular data is actually good to use - it can check for structural problems (blank rows and columns) as well as ensure that data fits a specific schema.
Tabular data in CSV and Excel formats is one the most common forms of data available on the web - especially if looking at open data. Unfortunately, much of that data is messy with blank and incorrect rows, and unexpected values for some fields. (For example, date columns that do not feature well-formed dates. See here for more examples of "bad data".)
That’s where Good Tables comes in: it checks your data for you, giving you quick and simple feedback on where your tabular data may not yet be quite perfect.
