Webxcel creates a full-fledged RESTful web backend from your Microsoft Excel workbooks. It is written in 100% plain Visual Basic macros and comes with a lot of handy tools to help you build the next big thing.
Build your web applications using the autogenerated RESTful CRUD endpoints and the static file server. Webxcel even supports mapping worksheet relationships, so you can model your table schema as flexible as you wish.
To configure a new table, simply insert your column names in the first row of an empty sheet and make the cell of your primary key bold. References to other tables can be introduced using fk_<table> columns and foreign keys:
When accessing GET /workbook/cities, webxcel will return a fully mapped JSON object:
[
{
"id": "1",
"city": "Seattle",
"states": {
"short_name": "WA",
"full_name": "Washington"
}
},
{
"id": "2",
"city": "Springfield",
"states": null
}
]No need to spin up a cloud server or function-as-a-service provider, implement rich server side logic right in Microsoft Excel using the built-in tools you already know and love. Using Microsoft Excel's immersive charting, you can gather even deeper insights from your data.
Webxcel supports scaling from a mere 10% to 400% for extreme detailed data insights. This makes it a perfect fit for small startups to global corporations. By default, webxcel projects are scaled 100%, but you can adjust this setting in the lower right corner of Microsoft Excel to fit your needs.
Many new devices come with Microsoft Office preinstalled, most of the time you won't have to do any setup at all. Deploying a project is as easy as dropping the file on the server and starting webxcel. Also backup is a no-brainer, simply copy and paste the project file to your backup location (e.g. a flash drive) and you're all set.
Webxcel is built on Windows Sockets 2 and runs on any Microsoft Excel version starting from Microsoft Office 2007, but should work on any macro enabled setup.

The build.ps1 PowerShell script creates an empty webxcel project in build/webxcel.xlsm, which you can alter to create your table schema. You can also import the classes and modules by hand, but this will consume considerably more time since the import dialog only allows you to select one file at a time.
Webxcel can be started using either the Main sub through the developer ribbon or by assigning it to an interactive component like a button. Once started, webxcel will serve all static files located in the same directory as your project's .xlsm.
During webxcel's runtime, Microsoft Excel will not respond. This is due to Visual Basic being executed on the main UI thread. As this is a known issue, webxcel creates a lockfile <project>.xlsm.lock, which you can delete to gracefully shut down the server. You also could force-quit Microsoft Excel, but this might result in the port being blocked from further usage until a reboot (webxcel will raise the error ErrorSocketBind whenever it can't bind to a specific port).
To contribute, clone the repository, build an empty webxcel project and start hacking in the Visual Basic editor (Alt + F11). Once you've finished your contribution, export your classes or modules and create a pull request. As Visual Basic is case-insensitive, please check your exported classes to minimize renaming commits (e.g. after introducing a new variable Dim name and the editor globally renamed Name to name).
