All importers should support option to import without changing data #478

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
It should be possible for users to turn off all unnecessary transformations of 
input data.  Many times these are irreversible, so the time to deal with them 
is at initial import.

One example is the XML importer has no way to turn off string->number 
conversion.  Other converters such strip leading and trailing double quotes 
that they find.

In r2451 TabularImportingParserBase now defaults guessCellValueTypes to False 
so that importers which don't specify it don't get it turned on automatically.  
This was adversely affecting Excel, Open Office Calc, and Google Spreadsheets 
because they had no control to turn off the default since they have data types 
built in.

I think most of the work is done for this and I'd like to clean up any loose 
ends and get it included in Refine 2.6.
