I am trying to import a .csv file which has columns of strings, reals and dates. Import keeps giving me the dates as DateObject, which make it difficult to export later on. How can I disable that feature when importing?

    $\begingroup$ Welcome to Mathematica.SE! Could you please share the code you use to import and few lines of a .csv file in the same format as have? $\endgroup$ – Johu Sep 11 '18 at 22:21
  • $\begingroup$ Also, please tell us how you want to represent dates in Mathematica if not as DateObject $\endgroup$ – m_goldberg Sep 12 '18 at 0:17

    $\begingroup$ Please show a complete example: a sample CSV files (2-3 lines are enough), and the precise Import command you were using. I cannot reproduce what you claim and the documentation seems to state that Import does not interpret dates by default. That has to be requested explicitly through the "DateStringFormat" option. $\endgroup$ – Szabolcs Sep 12 '18 at 7:06
  • $\begingroup$ Yeah, an example CSV file would be great. $\endgroup$ – Henrik Schumacher Sep 12 '18 at 7:13

If data contains an array of what you have imported, then you can convert all DateObjects into strings by data /. a_DateObject :> DateString[a].
