Have you encountered a problem with a TSV file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a TSV file here. In the further part of this page we have added a list of programs that should open your TSV file. It is enough you choose a proper application for your operating system, download and install it.


The TSV suffix identifies a data file whose values are separated by a tab instead of the more frequently used comma. It looks like a csv file. For these files, the extension tdl is used. The data can be imported by most spreadsheets, although the files are not directly supported.

TSV files are simple text files that can be opened and edited in any text editor.

How to open a TSV file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the TSV file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a TSV file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support TSV files. At this point we are looking for disk space where the application was installed in and we can link it with a TSV file. Since then, our operating system will use the selected program to support all TSV files.

Other issues

Despite the described problem with TSV there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the TSV file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the TSV file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
