csvprintf is a simple UNIX command line utility for parsing CSV files.
cvsprintf works just like the printf(1) command line utility. You supply a printf(1) format string on the command line and each record in the CSV file is formatted accordingly. Each format specifier in the format string contains a column accessor to specify which CSV column to use, so for example %3$d would format the third column as a decimal value.
csvprintf can also convert CSV files into XML and JSON documents.
You can view the ManPage online.
Examples
Given this input file input.csv:
NAME,ADDRESS,POINTS
Fred Smith,"1234 Main St.
Anytown, USA 39103",123.4567
"Wayne ""The Great One"" Gretsky", 59 Hockey Lane , 999999
here is the resulting output:
$ cat input.csv | csvprintf -i 'Name: [%1$-24.24s]\nAddress: [%2$-12.12s]\nPoints: %3$.2f\n'
Name: [Fred Smith ]
Address: [1234 Main St]
Points: 123.46
Name: [Wayne "The Great One" Gr]
Address: [59 Hockey La]
Points: 999999.00
An example of the XML output:
$ cat input.csv | csvprintf -iX
