ExTab

This is an API to map tables in excel files to java objects. It uses Apache POI to parse the excel files and provide a JPA styled annotation based mapping of objects to table rows.

###Reading a file

####1. Create a model class public class Employee { @ExcelColumn(order = 1, type = STRING) private String name;

  @ExcelColumn(order = 2, type = LONG)
  private Long employeeId;

  private String address;

  @ExcelColumn(order = 5, type = DOUBLE)
  private Double salary;

  @ExcelColumn(order = 4, type = DATE, format = "MM/dd/yyyy")
  private Date joiningDate;

  @ExcelColumn(order = 3, type = STRING)
  private void setAddress(String addr) {
    address = addr;
  }

  @RowNum
  private int itemRowNumber;
}

2. Create an excel file with following data

|Joe Hoe	    |420	|Lapatabad	|28-02-13	|83.435 |
|Woe Hoe	    |840	|Kyapatabad	|01-12-09	|75.432 |
|Jessa Hoe	  |1680	|Napatabad	|31-01-13	|114.232|
|Vessa Hoe	  |3360	|Kyapatabad	|11-01-12	|43     |

3. Read file

List<Employee> parsed = ExcelTableReader.read("/Users/batman/data/Employee.xlsx", Employee.class);

ExcelColumn

It maps a setter method or field with particular columns in the excel tables.

@ExcelColumn(order = 1, type = STRING)
	a. Maps the field/setter to the first column(one based index) in the excel table.
	b. All values in the column are expected to be of type text.

@ExcelColumn(order = 4, type = DATE, format = "MM/dd/yyyy")
	a. Maps the field/setter to the fourth column(one based index) in the excel table.
	b. All values in the column are expected to be of type date, formatted as "MM/dd/yyyy".
	c. For valid patterns of date formats refer java.text.SimpeDateFormat.
