The file belongs to the Windows version of BioShock, the first-person action game developed by Irrational Games and published by 2K Games. It contains the saved state of a player's game rather than game content intended for editing or reuse.
BioShock loads these files from its saved-game location and uses them to continue an existing game. This use of the .bsp extension is specific to BioShock.
Open the file from within BioShock for Microsoft Windows. Start the game and use its load-game function to select the saved game.
Opening the file directly in a text editor or another general-purpose program will not display the saved game in a usable form.
There is no practical general-purpose conversion for a BioShock saved game file. Its data is intended to be read by BioShock.
Do not rename the extension as a conversion.

PBASIC is a programming language used with BASIC Stamp microcontrollers and to program robot controllers. A BSP file provides input for the PBASIC preprocessor as part of that development workflow.
The format is associated with the BASIC Stamp Windows Editor on Microsoft Windows. The editor processes the file as PBASIC input rather than treating it as a general-purpose document format.
Open the file with the BASIC Stamp Windows Editor on Microsoft Windows. This is the appropriate program for processing BSP files as PBASIC input.
A plain-text editor may display the file contents, but it will not provide the BASIC Stamp-specific processing offered by the Windows Editor.
BSP files are intended as PBASIC preprocessor input, so they do not have a useful general-purpose conversion format. Keep the file in its original form when it is needed by the BASIC Stamp Windows Editor.
The file contents can be copied into another text document, but doing so may prevent the BASIC Stamp software from recognising it as its original input file.

Half-Life, Team Fortress, Counter Strike - 3D first person action game map file.
The format is similar but not identical to the BSP file formats of the Half-Life 1 engine, which is based on the Quake 1 and Quake 2 file formats, plus that of the later Quake 3.
The bsp file contains the vast majority of the information needed by the Source engine to render and play a map. This includes the geometry of all the polygons in the level, references to the names and orientation of the textures to be drawn on those polygons, the data used to simulate the physical behaviour of the player and other items during the game.
The location and properties of all brush-based, model (prop) based, and non-visible (logical) entities in the map, and the BSP tree and visibility table used to locate the player location in the map geometry and to render the visible map as efficiently as possible. Optionally, the map file can also contain any custom textures and models used on the level, embedded inside the map's Pakfile lump.
Use Valve Hammer editor to open *.bsp files.
Probably cannot be converted to other formats.
