MySQL 5.7 is GA and has over than 150 new features. One of them is a Native JSON Data Type and JSON Functions: “Allows for efficient and flexible storage, search and manipulation of schema-less data. Enhancements include a new internal binary format, support for easy integration within SQL, and index management on the JSON Documents using generated columns”.
I’m a big fan of the MySQL command line tool ie the default text client modestly named: mysql. I use it everyday because you can do almost everything with it (DML, DDL, DCL, administrative tasks,…).
It has many options including generate xml or html output.
$ mysql –help | grep “\–html”
-H, –html Produce HTML output.

One of my colleague asked me : « Is an ALTER TABLE with many specifications is faster than 1 ALTER TABLE by specification ? »
The answers seems quite intuitive, anyway figures are better than a long speech…
