ansible.builtin.csvfile – read data from a TSV or CSV file

Note

This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name csvfile even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 1.5: of ansible.builtin

Synopsis

  • The csvfile lookup reads the contents of a file in CSV (comma-separated value) format. The lookup looks for the row where the first column matches keyname, and returns the value in the second column, unless a different column is specified.

Parameters

Parameter Choices/Defaults Configuration Comments
col
string
Default:
"1"
column to return (0 index).
default
string
Default:
""
what to return if the value is not found in the file.
delimiter
string
Default:
"TAB"
field separator in the file, for a tab you can specify "TAB" or "t".
encoding
string
added in 2.1 of ansible.builtin
Default:
"utf-8"
Encoding (character set) of the used CSV file.
file
string
Default:
"ansible.csv"
name of the CSV/TSV file to open.

Notes

Note

  • The default is for TSV files (tab delimited) not CSV (comma delimited) … yes the name is misleading.

Examples

- name:  Match 'Li' on the first column, return the second column (0 based index)
  debug: msg="The atomic number of Lithium is {{ lookup('csvfile', 'Li file=elements.csv delimiter=,') }}"

- name: msg="Match 'Li' on the first column, but return the 3rd column (columns start counting after the match)"
  debug: msg="The atomic mass of Lithium is {{ lookup('csvfile', 'Li file=elements.csv delimiter=, col=2') }}"

- name: Define Values From CSV File
  set_fact:
    loop_ip: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=1') }}"
    int_ip: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=2') }}"
    int_mask: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=3') }}"
    int_name: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=4') }}"
    local_as: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=5') }}"
    neighbor_as: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=6') }}"
    neigh_int_ip: "{{ lookup('csvfile', bgp_neighbor_ip +' file=bgp_neighbors.csv delimiter=, col=7') }}"
  delegate_to: localhost
