Welcome to the Forums.
According to Wikipedia
https://en.wikipedia.org/wiki/Quicken_Interchange_Format the file structure looks, to me, to be more like a database, rather than a spreadsheet or importable text.
You might have better luck trying to use the .qif file with Base, rather than Calc.
I thought that Zamzar might be an option for doing the conversion, and you are welcome to see if they can do that conversion, but it's not listed in their list of standard file formats.... that doesn't mean they can't or won't convert it, just that, if they can (and will), you could be waiting for a while to get the converted document.
If you have access to Quicken or the software that made the .qif file, then I'd suggest that you see if there is another alternative for the file to be saved in.
