    printf "%" (length($i) > fmt[i] ? "." : "-" ) fmt[i] "s", $i           
  print x
  }' config.txt temp.txt

Needs some small modification i guess.
The input temp.txt

Code:

1       12      123     1234    1
A       AB      ABC     ABDC    e

config.txt

Code:

{
                        'name'  :       'Field1',
                        'type'  :       'input',
                        'spos'  :       1,
                        'size'  :       2,
                },
                {
                        'name'  :       'Field2',
                        'type'  :       'input',
                        'spos'  :       3,
                        'size'  :       2,
                },
                {
                        'name'  :       'Field3',
                        'type'  :       'input',
                        'spos'  :       5,
                        'size'  :       8,
                },
                {
                        'name'  :       'Field4',
                        'type'  :       'input',
                        'spos'  :       13,
                        'size'  :       11,
                },
                {
                        'name'  :       'Field5',
                        'type'  :       'input',
                        'spos'  :       24,
                        'size'  :       11,
                },

OUTPUT is as follows

Code:

1 12123     12341
A ABABC     ABDCe

Expected is

Code:

1 12123     1234       1
A ABABC     ABDC       e
