Hi,
Simplest method that comes to mind, is to save the excel as a CSV file and then
use the Add Delimited Text Layer.
Using this method you can specify which columns are the coordinate columns and
it can preserve the column headings and order.
Hope this helps,
Regards,
Richard.

Hi Riccardo,
You could try the Split with Lines tool available in the Processing Toolbox,
under Vector Overlay. Just use "Split" in the search bar to narrow down the
list.
Hope this helps,
Richard

Ignore my first line, it’s a typo. I got dragged away to something else, came

Im not quite sure what you are looking for, but if you are trying to reproject
a dataset from WGS84 to ITRF2014 you can use the Reproject Layer tool in the
Processing toolbox.

|| ' m' if you change this to round(100*( $length) ) || ' cm'
Hope this helps

Virtual fields are not saved as part
of the Layer, but as Part of the active project. You could though make them
permanent when you’re finished, by creating a new field and using the virtual
field as the source.
Hope this helps,

on your existing datasets, one further
thing you can look at is using Zoom Levels (Scale range) to stop the rendering
of data beyond a certain zoom level, only allowing you to view the data at
certain levels.
