Extract text from NS1 files
To convert your NS1 file to another format, you need NetStumbler or other Data software.
To convert other file formats to the "Wireless Log File" file type, you need software like NetStumbler or a similar tool.
The .NS1 file extension is most famously associated with NetStumbler, a legendary Windows utility used for detecting Wireless LANs (802.11b, 802.11a, 802.11g). These files are binary logs that capture granular data from a wireless scanning session, including SSIDs, MAC addresses (BSSIDs), signal strength (SNR), noise levels, and GPS coordinates if a receiver was attached.
Because the .NS1 format is binary (not plain text) and proprietary to an application that was last updated in the mid-2000s, it presents significant accessibility challenges. You cannot simply open an .NS1 file in Notepad or Microsoft Excel to view the data; doing so will display garbled machine code. Furthermore, running the original NetStumbler software on modern operating systems like Windows 10 or 11 is notoriously difficult due to driver incompatibilities and the lack of NDIS 5.1 support.
To make this data useful for modern analysis or heat-mapping, users typically convert .NS1 files into CSV (for spreadsheet analysis), TXT (for simple archiving), or KML (for visualization in Google Earth). A secondary, less common use for this extension is as a save state file for the Nestopia NES emulator.
Convert.Guru analyzes your NS1 file, detects the exact format, and lets you read the text inside.
Users also converted MOM, PAT and SM2 files.
If you want to convert NS1 file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use NetStumbler or similar software from the "Wireless Network Scan Log" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to NS1, try NetStumbler or another comparable tool in the "Wireless Network Scan Log" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NS1 converter.
