I have a website created in WordPress and would like to put an excel sheet on one page, so that a site visitor can enter different numbers and gives the sheet different outcomes.
The excel sheet is ready and exists but from 1 worksheet. The visitors may only enter the sheet and may not, of course, download, the sheet. After leaving the page must display the worksheet to the starting position.
NB in the sheet is also a chart, which is based on the entered numbers of the visitors.
WordPress provides here not in, not even through a plugin.
Is this possible with a converter to PhP etc., or how can I best deal with this?
