humanly readable dump of an SQL-Server database

I am looking for data, but I don't know the name of the table, neither of the column. As you might know, it's possible to create the backup of an SQL-Server database. Launching a grep on that backup indeed reveals that the mentioned data exist, but it does not mention the name of the table and/or column. Is there a way to find data inside an SQL-Server database, either by some SQL, either by creating a human readable textfile from a DB? Thanks in advance
