Please, see the screen shots attached. I selected to open a foreign data as workfile, it opened the data series, but it did not recognize the date column as dates and I cannot open the file as a data series only as a unstructured data.

This happens frequently in different type of files and I couldn't find a reason for this yet. I selected to send you a very simple file as an example of one of the cases this is happening

That file doesn't contain a valid date series. If the Excel file doesn't contain a valid date series, EViews won't be able to select a date series.

That's the issue, I know, but why is this a non valid date series ? This are date series downloaded directly from yahoo finance or google finance, what can I do as a process to find the error and fix it ? tks

Generally if EViews refuses to auto-recognize a date series it is because there is something wrong with that date series

Gareth, I tried with a file that seemed to be a correct data set, and it worked the same....This one is a direct download of BXP ticker from yahoo finance, see attached

Gareth, I found out what is going on...I use Quandl to download the data in Excel, however Quandl is delivering the dataset with missing dates both through Google and Yahoo
