- It is advisable to periodically back up this data (txt format), in order, for example, to find it again if you change computer, browser, or if you delete 'site data' in your browsing history.
This backup can also be used as an export, to allow import into calagenda, on another computer, on your tablet or phone, or in another browser. - The csv format is suitable for importing into a spreadsheet (Excel, LibreOffice, OpenOffice, ...).
- The xml format is more for developers who want to interface calagenda with another tool.
