Importing CSV format data logs to non-USA/UK versions of Microsoft Excel
Data log files are in the comma-separated values (CSV) file format. You can open these files
directly in Excel from the Data Logs page when your system is running the USA or UK
version of Excel. In other countries, however, this format is not widely used because
commas occur frequently in numerical notation.
To open a data log file that you have saved, follow these steps for non USA/UK versions of
Excel:
1. Open Excel and create an empty workbook.
2. From the "Data > Import External Data" menu, select the "Import Data" command.
3. Navigate to and select the data log file you want to open. The Text Import Wizard starts.
4. From the Text Import Wizard, change the default option for "Original data type" from
"Fixed width" to "Delimited".
5. Click the Next button.
6. From the Step 2 dialog, select the "Comma" check box to change the delimiter type from
"Tab" to "Comma".
7. Click the Next button.
8. From the Step 3 dialog, you can optionally change the Date format from MDY
(month/day/year) to another format.
9. Complete the remaining steps of the Text Import Wizard to import the file.
