Message - Failed to connect to the Excel workbook. Probably, it happened because of too many open connections

This error occurs when you are trying to read data from a CSV or an Excel file, and TestComplete fails to connect to the file.

To read data from a CSV or an Excel file, TestComplete creates a connection to it. If there are already many open connections to the data source, TestComplete may fail to open another one. This may happen because some drivers limit the number of simultaneous connections.

• In your tests, call the DBTableVariable.Disconnect methods for all the DBTable variables you do not use anymore.

• In your tests, call the DDT.CloseDriver method to close the connection opened by a driver.
