If you just want to see what’s in the database without installing anything extra, you might already have SQLite CLI on your system. To check, open a command prompt and try:
sqlite3 database.sqlite
Replace database.sqlite with your database file. Then, if the database is small enough, you can view the entire contents with:
sqlite> .dump
Or you can list the tables:
sqlite> .tables
Regular SQL works here as well:
sqlite> select * from some_table;
Replace some_table as appropriate.
