DateTime columns incorrectly read from CSV with European locale

We have a problem reading a CSV file with DateTime columns in it (see attached file).

We are located in the Netherlands, where the DateTime format is dd-mm-yyyy.
When I read the attached file and let Aspose “guess” the type of the columns, it correclty guesses that all 4 columns are DateTime.
However, it converts 01-02-2012 to January 2, 2012 in stead of February 1, 2012, as if the locale was EN_us (mm-dd-yyyy). The same goes for 01-02-2013 and 01-40-2014 in the example file: day and month are swaped.
However, as soon as this pattern does not “fit” a US date format any more, it uses a European locale:
31-7-2015 is correctly converted to July 31, 2015.
The end result is a workbook with many (but not all) dates incorrect.

This is the Java code we use:
TxtLoadOptions options = new TxtLoadOptions( type );
options.setLocale( new Locale(“nl”, “NL”) );
options.setRegion( CountryCode.NETHERLANDS );
options.setEncoding( Encoding.getUTF8() );
Workbook workbook = new Workbook( stream, options );

We are using Aspose.cells 7.5.2 for Java.

Hi Wim,

Thanks for your posting and using Aspose.Cells.

I have tested this issue with the latest version: Aspose.Cells
for Java v7.7.2.3
and found that Aspose.Cells recognizes both type of values e.g 23-01-2013 and 01-23-2013 as dates. The first value will is treated as dd-mm-yyyy and second value is treated as mm-dd-yyyy.

So locale or regional setting does not have any effect. Could you please test your issue with the above version and let us know your run results.

Java


String filePath = “F:\Shak-Data-RW\Downloads\datetime.csv”;


TxtLoadOptions options = new TxtLoadOptions(LoadFormat.CSV);

options.setLocale( new Locale(“nl”, “NL”) );

options.setRegion( CountryCode.NETHERLANDS );

options.setEncoding( Encoding.getUTF8() );

Workbook workbook = new Workbook( filePath );


Worksheet worksheet = workbook.getWorksheets().get(0);


Cell cellA1 = worksheet.getCells().get(“A1”);

Cell cellB1 = worksheet.getCells().get(“B1”);

Cell cellC1 = worksheet.getCells().get(“C1”);

Cell cellD1 = worksheet.getCells().get(“D1”);


System.out.println(cellA1.getType()==CellValueType.IS_DATE_TIME);

System.out.println(cellB1.getType()==CellValueType.IS_DATE_TIME);

System.out.println(cellC1.getType()==CellValueType.IS_DATE_TIME);

System.out.println(cellD1.getType()==CellValueType.IS_DATE_TIME);


workbook.save(filePath + “.out.xlsx”);
