When Importing an Excel file with Zip and Zip +4- import errors if 1st row contains Zip (and not zip+4)

When Importing an Excel file with Zip and Zip +4, import errors if 1st row contains Zip (and not zip+4)

For example, if the first row contains zip+4, Aspose imports all remaining records as text (which is fine).

However, if the first row contains only a numeric zip, then the first occurence of a alphanumeric field (ex. 21202-1234) will cause the import to fail.

Formatting the field in the Excel template as TEXT does not work. The only work around so far is to make the first row a zip+10. However, this is not a good work around because we are expecting end-user quality data (i.e. junk, zip, zip+4)!

Thank you in advance!

We are not clear about the problem you mentioned.

Could you give us more details and do create a console application and post us here with all the files (input/output file, other files etc.) to show and reproduce the problem. We will check and fix it soon if found the problem.

Thank you,


By the way, if you are exporting data to fill a datatable, I think you may try the attached version( using Cells.ExportDataTable(DataTable dataTable,int firstRow, int firstColumn,
int rowNumber, bool exportColumnName) method to export the data table.

This error might be caused by there are mixed value types in the column(s).


Workbook workbook = new Workbook();
Cells cells = workbook.Worksheets[0].Cells;
//Create a datatable and add columns to it.
//NOTE: If there are mixed value types, please always use String data types for those columns.
DataTable dt = new DataTable();
dt.Columns.Add("column1", typeof(string));
dt.Columns.Add("column2", typeof(string));
dt.Columns.Add("column3", typeof(string));
dt.Columns.Add("column4", typeof(double));
dt.Columns.Add("column5", typeof(double));
dt.Columns.Add("column6", typeof(double));
dt.Columns.Add("column7", typeof(double));
cells.ExportDataTable(dt, 0, 0, 232, true);
workbook.Worksheets["NewSheet"].Cells.ImportDataTable(dt, true, "A1");

Kindly let us know if it works fine now, if you still could not figure it out, kindly do post your template file and sample codes (you may create a demo app too to post us here)

Thank you.
