### fixedtocsv

Convert a data-positioned (fixed width) file to CSV format.

```go

go get -u github.com/Guitarbum722/fixedtocsv

cd fixedtocsv

make build

```

#### Usage:

```

Usage: fixedtocsv [-c] [-d] [-f] [-o]

        Options:

          -h | --help  help

          -c           input configuration file (default: "config.json" in current directory)

          -d           output delimiter (default: comma ",")

          -f           input file name (Required)

          -o           output file name (default: "output.csv" in current directory)

```

The only required flag is `-f` which specifies the input file.

A JSON or CSV file is expected to provide the configuration of the input data (being the fixed width flat file).

Currently, a file named `config.json` is expected by default.  Please see the flags above to specify a different file name.

Here is an example of the configuration file.  Most importantly, each object in `columnLens` represents a field in the file.  The order of the fields will be evaluated in the order in which they appear in the JSON.

```json

{

    "columnLens": [

        {

            "start": 0,

            "end": 6

        },

        {

            "start": 7,

            "end": 21

        }

    ]

}

```

If you want to use a CSV for the configuration, then it should have the below format (headers are expected).  You will need to use the `-csv` option AND the `-c` flag with a file name is REQUIRED in this case.

```

column,start,end

0,0,6

1,7,21

2,22,38

3,39,63

4,64,101

5,102,136

6,137,149

7,150,163

```
