Hi

I am using apache poi api to read data from the excel file and having problem with particular data format.

One of the coumns in the excel file had formula type whose value will be in the below format

"2001-160101100-22110-0000-000"

Note : the no of digits between each dash and the number of dash itself may vary but the format will always be numbers followed by - and end with numbers.

The api successfully find the field type as formula and consider it as numeric type but it throws NumberFormatException as it contains -.

I am using DataFormat class to read all the numeric cell value as we need to read the data as it is (no round up or truncate) in the cell value.

I was going through the genral format available in the api but could not understand how to add custom format to the list of available formats.
I was trying to use DataFormat.addFormat(String,Format) from the api but did not understand what to pass in the String argument and how to define the Format for this custom format.

Your help is appreciated.
