Excel (@hint/formatter-excel)

The excel formatter outputs the results in an Excel file (xlsx),
each resource in its sheet:

!Example output for the summary sheet of the excel
formatter

!Example output for one of the details sheet of the excel
formatter

The file will be created in the folder where webhint is called from
(i.e.: process.cwd()).

To use it you will have to install it via npm:

``bash
npm install @hint/formatter-excel --save-dev
`

Note: The recommended way of running webhint is as a devDependency of
your project.

And then activate it via the [.hintrc][hintrc] configuration file:

`json
{
"connector": {...},
"formatters": ["excel"],
"hints": {
...
},
...
}
``
