I have been working with TSV files for months, but I have one file that refuses to be opened in LibreOffice Calc. It instead brings it up in writer. This behavior is consistent across command line and from the file open dialog.
I am using LibreOffice 18.104.22.168
One line of the file being opened looks like this:
-1.7707604 -0.50868493 -1.0049824 -1.0982082 -1.5262277 -1.505284 -1.0780258 -1.2065934 #1 cheat: chess with friends edition #1 Cheat Words With Friends Edition <page>\n <title>df75f611bd836c15388067608d87463b</title>\n <ns>0</ns>\n <id>0</id>\n <timestamp>?</timestamp>\n <text >\n#1 Cheat Words With Friends Edition\n\n???
