New Workbook with csv file results in java.lang.IndexOutOfBoundsException: millisecond


we tried to load a csv file we received which resulted to a IndexOutOfBoundsException

for reproduce this issue you need just a empty file with test.csv and the following line:

20200430;2020-05-01 04:45:06.99953;

java.lang.IndexOutOfBoundsException: millisecond
at com.aspose.cells.DateTime.(Unknown Source)

a conversion from this timestamp would work
2020-05-01 04:44:37.38364
and is converted to
2020-05-01 04:44:37,384

with 999 it seems round up is not possible anymore and there is the IndexOutOfBoundException thrown

I would like to ask if it is possible to fix this issue either with an option (don’t care about wrong conversion) in TxtLoadOptions when create new Workbook
(as I only found an option to deactivate the whole dateTime conversion setConvertDateTimeData(false) which we would not want to use, because we would like to have a conversion)
or just convert it with a overflow to the right date, or in case of error just import it with string and warning, instead of an exception

we used the following TxtLoadOptions for new workbook

String separator = ";" // in this case
separatorChar = separator.charAt(0);
			loadOptions = new TxtLoadOptions(LoadFormat.CSV);

			ByteArrayInputStream stream = new ByteArrayInputStream(Files.readAllBytes(path));

			workbook = new Workbook(stream, loadOptions);
		catch (Exception e)
			// exception is happening here  

best regards,


Thanks for the sample code segment and details.

After an initial test, I am able to reproduce the issue (found your exception) as you mentioned by using the following simplest sample code with the attached file. I also noticed by using setConvertDateTimeData(false), the issue is not occurred, then you do not want to use this option.
Sample code:

String path = "f:\\Files\\test1.csv";
        String separator = ";"; // in this case
            char separatorChar = separator.charAt(0);
                            TxtLoadOptions loadOptions = new TxtLoadOptions(LoadFormat.CSV);

                            Workbook workbook = new Workbook(path, loadOptions);//exception
