For saving data note the following:

  • The file must be saved in .csv format. (Keep file extension!)
  • The browser will offer the ?table.csv? filename as default. Rename the file describing its contents, or the name of the respective index.
  • Depending on the given computer settings, it is possible, that instead of downloading, the index data file is automatically opened in MS Excel, or Open Office. In this case do not save the file from Excel or Open Office as .csv (the original file format is changed, when doing so). --

To avoid opening .csv files with other software, right-click the ?Download to Spreadsheet? URL, and:
