In case you are having difficulty extracting the data from the National Index and you are not sure what the problem is, it may help to download the sample National Index File and compare it to the file you are having problems with.

If you are trying to create your own Aggregated Data File, it may be useful to download the samples below, so that you are confident that the file you are creating is in one of the correct formats.  Three versions of the Aggregated Data File are available, one in tab-delimited format, one in comma delimited format and one in the CSV format.

Any of the sample files can be uploaded to this facility using the appropriate upload page.  

If instead of downloading, any of the above files opens in a new browser page, click on your browser's Back button and right-click on one of the above links. Select 'Save Target' or 'Save Link' (depending on your browser) to save the file to disk.
