问题
I have realm database (.realm) from an existing application, which has more than 400k records.
I dug my head in to this for more than 3-4 hours, but I couldn't find any fruitful results towards converting a .realm file in to a sqlite file.
回答1:
Any data conversion so far has been done manually. People have converted from Core Data to Realm by grabbing the objects from Core Data and then saving them to a Realm.
I imagine your best bet will be similar here. Grab each object from the Realm and then convert it to the tables/rows/and columns in sqlite. Then you can take that file anywhere.

I'm not at home with this, but I found this link hopefully it can help.
回答3:
You can open the realm file in Realm Browser & there you have the option to convert the file in to CSV ( File => Export => CSV ). Then you can import that CSV file to mysql database.
If you want sqlite more specifically, You can import tables separately to your sqlite db through SQLiteBrowser . Create or open your database file and select the specific table you want , then you can import table from CSV.
