Creating and Opening Excel Files

Applies to TestComplete 15.42, last modified on September 08, 2022

In TestComplete tests, you can create Excel files or access already existing ones.

In Script Tests

The following steps are required:

  1. Get access to a file. To create a new file, use the Excel.Create method. To access an existing file, use the Excel.Open method.

  2. Get access to a worksheet. You can specify the worksheet by its title or index. For this purpose, use the SheetByTitle or SheetByIndex methods respectively.

    // Write the data into a new row of the Excel file
