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)
Most often resolving problems with opening CSV files is very simple. Just install an appropriate program that supports such files. All of the listed programs support CSV files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of CSV files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate CSV files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Microsoft Excel applications is not on the list, select "Browse" option in order to manually locate the directory where Microsoft Excel has been installed.
Sometimes problems with opening CSV files may not lie with the application itself, but can arise due to other causes, such as:
