What is a .TWB file?
Plain text that programs, servers and people write every day.
A .TWB file is a Tableau Workbook File used for data visualization and analysis. It contains the instructions and formatting for a data project, including dashboards and worksheets, but does not include the source data itself. These files are typically opened and managed using Tableau Desktop.

Frequently asked questions
Is my .TWB file uploaded anywhere?
No. The file is read and highlighted for you.
Why do some characters look wrong (é, ł)?
That usually means the file was saved in one encoding and opened in another. We detect UTF-8, UTF-16 and the Windows-1250/1252 code pages automatically and show which one was used.
Can it handle huge log files?
Yes, up to 50 MB. Only the lines on screen are drawn, so scrolling stays smooth. Syntax colours are switched off for files over 1.5 MB to keep things fast.
How do the log level filters work?
We find levels like ERROR, WARN, INFO and DEBUG on each line. Lines without a level, such as stack traces, stay with the entry above them, so filtering to errors keeps the full trace.
Can I edit the file?
This is a viewer. To change code, download it or copy it into your editor. Converting encodings and line endings is planned.
