When I open a CSV exported from SQLite, Microsoft Excel erases the zeros which are codes, e.g. 000.11 instead of 11.
How can I keep the leading zeros?
Import the column as Text or change the format to display the number. Reminder, the 0 at the left of number are not part of the number so 0001 is the number 1. If in your application 0001 is different from 1 then you are dealing with strings (or text) not numbers ...
'
. it will automatically be interpreted as text upon import.
