As a developer designing application and implementing Databases is an everyday task. Having realistic data for testing and implementing the application or the API can be a boring job. Here comes this tool I found called Mockaroo.
All you need to do is specify the columns you want and the data type and it generates any data you want.
It contains data types for pretty much anything you can think of and if there is something more specific you can use regular expressions to generate it.
You can generate up to 1000 rows on the following formats. Choosing SQL gives you also an option to create the table!
What kind of data generation tools do you use? Leave your suggestions in the comments!
