Generating Reports with Other Apps
Cordelia deliberately doesn't try to be a reporting or analytics tool itself. Other tools already do that well. Cordelia focuses instead on getting your Garmin data into open, standard forms those tools can read directly.
Working from the database
The SQLite database Cordelia creates can be queried directly by anything that speaks SQLite: spreadsheet software with a database connector, business intelligence tools, notebooks in Python or R, or plain SQL queries run from a database browser.
Working from an export
If your reporting tool prefers a file rather than a live database connection, export to JSON, CSV, or Microsoft Excel (see Exporting to JSON, CSV and Microsoft Excel) and import that file into the tool of your choice: spreadsheets, dashboards, or whatever else you already use.
Don't have a database yet?
See Example Cordelia Databases for six ready-made databases to practice against, plus a link to example Python report scripts.
