To preview flat file source and target data:
  1. Select a flat file source or target definition in the workspace.
  2. Right-click the source or target definition in the workspace and choose Preview Data.
  3. Click the Browse button to select a flat file.
  4. Locate and select the file you want to preview and click Open.
  5. Select a code page from the Preview Data dialog box.
    The code page must match the code page of the source. If the code page does not match the code page of the source, the data might display incorrectly.

    The Preview Data dialog box can display up to 500 rows and up to 65,000 columns.
  7. Click Open.
    The Preview Data dialog box displays shift characters display as periods (.) in shift-sensitive flat files.
  8. To change the starting row number or the number of rows you want to preview, enter a new number and click Refresh.
