How do I import numbers from a text document to a cell or cell area in Libre Calc?

Hi all,
I have a lot of text documents to copy into Libre Calc sheets. I can’t do regular file import because there is other stuff in the sheet as well. I would like to have either each cell call numbers from the text document, or import the file into a certain cell range/area of the sheet. Is there a function for this? If not, a way to write a script that would do this? The text files are all organised into columns by being tab or space delimited.

Thank you very much!

Select data in text document and copy it to clipboard.

Switch to workbook and select top-left cell of range to paste.

Use Paste Special - DDE Link

hi JohnSUN,
thank you a lot for the answer. i was looking for a solution that didn’t involve using copy/paste because this is very time consuming when there are a lot of sheets! do you know of anything more automated or command-like that lets you grab files? any idea if i can use a macro or something for this?
thank you!!
