Can I copy 1 calc sheet multiple times in one go?

I have made one sheet, a bingo card and wanted to copy it about 400 times. Is there an easy way to do this?
I have been doing it one by one and it is taking ages!

Creating the 400 sheets with right-click on sheet tab, select insert sheet and do accordingly.

Go to sheet to copy, select all [Ctrl+A]

Copy [Ctrl+C]

Select all other sheets by clicking the tab of first where copy, while keeping the [Shift] key pushed click on the tab of the last sheet, so they are selected.

Paste [Ctrl+V]

If the answer solves your question please tick the :heavy_check_mark:.

In one way it did work… But in another it didn’t

It has now changed all of the inputs from stuff like;

=IF(ISERROR(VLOOKUP(A1,$List.A5:E49,2,0)),"",VLOOKUP(A1,$List.A5:E49,2,0))

to

=IF(ISERROR(VLOOKUP(A1,$#REF!.A5:E49,2,0)),"",VLOOKUP(A1,$#REF!.A5:E49,2,0))

So the values I have in a list will not be automatically inputted into their locations (there’s lite 30 of these Look ups on each sheet)

What version of LIbreOffice?

Version 5.0
