Opening Text and CSV Files


There are several ways to open text tables and CSV files in Database Tour:

1. Opening through connection string. Select ADO interface, then choose Connection string option and write a connection string. This way is very flexible and allows to specify additional parameters in the connection string and override standard Database Tour connection behavior. It is recommended for advanced users. Here are basic connection strings (more examples and details can be found in the Internet):

Provider=Microsoft.Jet.OLEDB.4.0;TEXT;DATABASE=C:\MyCSVFolder;   (32 bit)

Provider=MSDASQL.1;Extended Properties="DefaultDir=C:\MyCSVFolder;Driver={Microsoft Text Driver (*.txt; *.csv)};DriverId=27;Extensions=asc,csv,tab,txt;"

Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=C:\MyCSVFolder;Extensions=asc,csv,tab,txt;   (32 bit)

Driver=Microsoft Access Text Driver (*.txt, *.csv);Dbq=C:\MyCSVFolder; Extensions=asc,csv,tab,txt;   (64 bit)

2. Opening through ODBC DSN. Create (if it does not exist yet) an ODBC DSN of the corresponding type using Windows administrative tools, and point it to the database. Then:

- Select FD interface, click ODBC, then point the Data source parameter to the ODBC DSN by selecting it from the drop-down list.


- Select ADO or BDE interface, then choose ODBC data source option and then select the needed ODBC DSN from the drop-down list.

3. Opening through BDE alias. Select BDE interface, then choose Alias option and then select the needed alias from the drop-down list. But first, you should create the alias of type STANDARD using BDE Administrator tool or Tools | BDE | Aliases menu of Database Tour, and point it to the folder where the files are located.

4. Opening by specifying file name. Select ADO or BDE interface, then choose File option and then browse for the needed file.

5. Opening by specifying folder name. Select ADO or BDE interface, then choose Folder option, select a driver from the drop-down list, and then browse for the needed folder.


  1. If you have problems with opening text or CSV file in Database Tour or its field structure is not as you expected, it probably means that the file does not have a schema describing its field structure or the schema was incorrectly defined.
  2. When choosing the ODBC option, please make sure the corresponding ODBC driver installed and the bit-version of it matches the bit-version of the application (32 or 64).
