Fixed Width Data splitting on LibreBase

I have data in pure text form not comma no tab no space etc it contains data in Fixed width I want to split it when importing to Libre Base how can I do it? Don’t want to use Calc etc for text to column. But some SQL

Hello,

SQL is only for use on data already within a database. Need to use some other means. Calc is probably the best option. From there, with correctly separated data, you can copy & paste into a Base table.
