Every time you sync a spreadsheet file (such as .ods from Ooo / LibreOffice) a gsheet link is generated on your computer so you can quickly access the file. Which means that ods to gsheet conversion is not a file conversion in proper sense, as the .gsheet file is just a link, not the actual spreadsheet. As such, you cannot open the link in your spreadsheet program, you have to open the link in Google Sheets and download your spreadsheet from there.

Unfortunately, there is no detailed software record in the database that match this conversion.
ODS
Files with ods file extension can be nowadays commonly found as spreadsheets saved using Calc program from OpenOffice.org, LibreOffice and perhaps other office productivity bundles that use documents based on OpenDocument Format schema.
GSHEET
Files with gsheet extension are URL links to a spreadsheet created in Google Drive. It is not the actual spreadsheet, just an URL link. You can download the spreadsheet from Google Drive in more typical format, like *.xlsx or *.ods.
