I think this should be made specific to CSV writer. Any reason you did not make it that way? Tab writers work well as they are and this fix would there only introduce new ambiguities. |

Ignore the previous comment. I need to check what did it do in write/read combination. If the old .tab behavior was already broken, I have no objections. |

Our tab saving was also broken, because it saved a string |

Issue
Fixes #6527.
Description of changes
The function that creates a string representation for storing values in file didn't expect that a
StringVariablecan benp.nan. Now it does.Our handling of StringVariable unknowns is a mess; the Table widget will apparently sometimes show
nan. This must be solved in general. The present PR only fixes the crash in saving of Excel files.Includes
