csvfile – read data from a TSV or CSV file

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
-
Default:
"1"
column to return (0 index).
default
-
Default:
""
what to return if the value is not found in the file.
delimiter
-
Default:
"TAB"
field separator in the file, for a tab you can specify "TAB" or "t".
encoding
-
Default:
"utf-8"
Encoding (character set) of the used CSV file.
file
-
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') }}"

If you notice any issues in this documentation, you can edit this document to improve it.

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
