Have you encountered a problem with a CSV 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 CSV file here. In the further part of this page we have added a list of programs that should open your CSV file. It is enough you choose a proper application for your operating system, download and install it.


CSV files contain data which are stored in the so-called Comma Seperated Values Format, ie comma separated values format. The CSV format is mainly used to exchange data between different databases or spreadsheets.

Each line of a CSV file stands for a record, while the values for each field (database) or cell (spreadsheet) are separated by commas in this line. Cell titles (eg for Excel) can also be specified, but there may also be problems with the exchange.

Especially when importing a CSV file into an already existing database or table, the order of the values should be agreed, as otherwise the values may be written to the wrong cells or data fields.

CSV files can be opened and edited with any text editor. In addition, CSV files can be imported from Microsoft Excel, OpenOffice Calc and also many database programs such as Mysql or Oracle and also exported. For some programs you can also specify the delimiter when importing or exporting (eg semicolon, dot)

How to open a CSV file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the CSV 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 CSV 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 CSV files. At this point we are looking for disk space where the application was installed in and we can link it with a CSV file. Since then, our operating system will use the selected program to support all CSV files.

Other issues

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

- verify that the CSV 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 CSV 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.
