Database exports are raw .sqlite files, intended mainly for sharing among iOS devices and backing up. Roastmaster data is much too complex to be viewed in a spreadsheet. They may open, but won't be in any readable format. Naturally, you can open the data in an SQLite editor, and glean anything you wish, but this would require SQL knowledge to infer the relationships of the fairly complex data tables.
Spreadsheets can only read delimited text files (.txt). The only objects Roastmaster can export as text files are reports. These are accessed in Utilities > Reports, and will give you aggregated, normalized data about the bean data for inventory, roasts, blends, etc. - suitable for manipulation in a spreadsheet.
Are you looking to export a series of roasts, with bean information, variables, and perhaps curve data? If so, that's on the feature request list. I try to prioritize features by demand, and though I haven't received a large number of requests for it, I've already started working on it. In fact, some dormant code already exists in the app in preparation for adding it to the reports section.
If you're interested, I'd be willing to work on it with you in prep for the next update. I'd need to know exactly what information you're after.
Please advise.
