What is a TAB file?
A .TAB file is a data file format. The exact content depends on the software that created it. Most commonly, a .TAB file contains Tab-Separated Values (TSV). This is a plain text format where tabs separate the data fields. You can open these with spreadsheet programs like Microsoft Excel or standard text editors.
Alternatively, it can be a geographic data table file used by MapInfo Professional for Geographic Information Systems (GIS). It holds spatial map data or attributes. It might also be a Guitar Tablature file for music editing software like Guitar Pro or TuxGuitar. Other uses include a 'Typinator Set File' for Ergonis Software products, an IBM MQ channel definition table, or game data for titles like The Witcher 2.
How to open TAB files?
Because the .TAB extension is shared among many different applications, finding the right software can be difficult. viewer.online/tab analyzes .TAB files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
If your file contains text data, you can often rename the extension to .TXT or .CSV to import it into database or spreadsheet tools. For structured data conversion, we recommend converting your files to sensible target formats on convert.guru. You can easily convert tab-separated text data into standard .CSV, .XLSX, or .JSON formats.
Software and tools
Depending on the specific format, popular tools include Notepad++ for text and code, QGIS or MapInfo for spatial data, and IBM MQ Explorer for server configuration files.
