Possible file formats conversion

Is there a list that details the possible file formats conversion and the exact parameters for each type of format?

Do you want to know which formats you can open in LibO or in which non-native formats you can save LibO?

Generally speaking, file conversions are best done on a like-for-like basis i.e., word processing to word processing, spreadsheet to spreadsheet, etc. It is however possible to convert most file formats to plainer formats, such as text. The accepted answer in this thread gives clear instructions on where to find the list of available filters, and how to obtain the required information from each for use with the --convert-to parameter.
