A simple python script to convert Nmap output to CSV


  • Support of Nmap version 5, 6, 7 normal format output (default format, -oN option)
  • Support of Nmap any version Grepable format output (-oG option) and XML (-oX)
  • Parsing main information : IP, FQDN, rDNS, MAC address and vendor, open ports, tcp/udp protocols, listening services and versions, OS, Number of hops to the target, and script output
  • Custom output format following the main items


Pass the Nmap output via stdin or from a specified file (-i).
The processed dump can be collected at stdout or to a specified file (-o).


usage: nmaptocsv [-h] [-i INPUT] [-x XML_INPUT] [-o OUTPUT] [-f FORMAT] [-S]
                 [-d DELIMITER] [-n] [-s]

optional arguments:
  -h, --help            show this help message and exit

Mandatory parameters:
  -i INPUT, --input INPUT
                        Nmap scan output file in normal (-oN) or Grepable
                        (-oG) format (stdin if not specified)
  -x XML_INPUT, --xml-input XML_INPUT
                        Nmap scan output file in XML (-oX) format

Output parameters:
  -o OUTPUT, --output OUTPUT
                        CSV output filename (stdout if not specified)
  -f FORMAT, --format FORMAT
                        CSV column format { fqdn, rdns, hop_number, ip,
                        mac_address, mac_vendor, port, protocol, os, script,
                        service, version } (default: ip-fqdn-port-protocol-
  -S, --script          Adds the script column in output, alias for -f "ip-
  -d DELIMITER, --delimiter DELIMITER
                        CSV output delimiter (default ";"). Ex: -d ","
  -n, --no-newline      Do not insert a newline between each host. By default,
                        a newline is added for better readability
  -s, --skip-header     Do not print the CSV header

Nmap Normal format (default output format -oN)

Dependencies and installation

  • A Python interpreter with version 2.7 or 3.X
    • Python 2.6 works with .nmap and .gnmap files but not with .xml ones
  • The easiest way to setup everything: pip install nmaptocsv and then directly use $ nmaptocsv
    • Or git clone that repository and pip install -r requirements.txt and then python nmaptocsv.py


  • version 1.6 - 06/13/2019: Python 3 support
  • version 1.5 - 09/30/2018: few bugs fixed in XML parsing + script alias format added
  • version 1.4 - 08/16/2018: few bugs fixed + XML parsing implementation
  • version 1.3 - 08/13/2018: fixing the README layout on PyPI
  • version 1.2 - 01/07/2018: script output parsing addition
  • version 1.1 - 01/07/2018: Cleaning the code, fixing some parsing bugs, delimiter option addition and made newline default
  • version 1.0 - from 2012 to 2013
