Web enabled spreadsheets are JavaScript forms that utilize Microsoft
Excel's calculation engine to provide advanced functionality to HTML forms.
Building complex HTML forms with Excel is much easier than with other technologies.

Created in Excel and then web-enabled with the SpreadSheetConverter add-in, most spreadsheet functions and formulas are available, so calculations, look-ups, conditional formatting and custom validation can be incorporated as required.
  • forms can be stand-alone or pass data back to processing scripts
  • calculations can utilize over 230 Microsoft Excel 2019 functions
  • WEBSERVICE() function can query SQL databases and web services
  • submitted data can be reloaded into calculations for adjustment
No matter how complex the form all proprietary business logic remains safe because forms are encrypted at generation and will only run on a specific designated web site.
