Add support for Microsoft Excel

Is your feature request related to a problem? Please describe.

Not able to parse excel files!

Describe the solution you’d like

Add support for an excel parser like https://github.com/SheetJS/sheetjs to also support xlsx

Something like: await this.$content(excel).only([sheet]).fetch()

Describe alternatives you’ve considered

• Export all seperate tabs as csv and import with ‘content’ as array of objects
• Parse with a server api

To be honest, I think supporting a proprietary format that is very uncommon in web development compared to one of the most common file/media format would not really help the module. This would basically mean that the project could be bloated with parsers for countless spreadsheet/table formats. The much more straight forward approach would be to convert your data from xls/xlsx/csv to json and let nuxt content do the rest. JSON is the widest and most optimized format for the usecase of nuxt content, which is providing a file system based database to query from. Think of some kind of minimal filesystem based MongoDB implementation.

In case you need inspiration, our VueJS demo includes a neat example

The index.vue page is not particularly interesting (it really should just reuse a CSV example)

The nuxt.config.js file uses extendParser to listen to a number of file formats. It generates an array of JS objects per worksheet.

A sample file can be placed in the content folder
