Possible Field Types

Dimension, Measure


One of the default value formats listed below, or the name of a format you created with the named_value_format parameter


The value_format_name parameter enables you to format Looker cells using built-in or custom format names. If you want to format Looker cells using Excel-style formats, use value_format instead.

The value_format_name parameter can be used on both dimensions and measures. For example:

measure: total_order_amount { type: sum sql: ${order_amount} ;; value_format_name: usd }

Default Format Names

Looker has the default formats shown in the tables below. When using one of the default formats, Looker rounds up or down to remove digits, rather than truncating values. When a default format name is used on a measure, rounding occurs after the measure has been aggregated.

You can also create your own named formats by using the named_value_format parameter.

The default formats for numeric field types are:

Name Example
decimal_0 1,234
decimal_1 1,234.5
decimal_2 1,234.56
decimal_3 1,234.567
decimal_4 1,234.5678
usd_0 $1,234
usd $1,234.56
gbp_0 £1,234
gbp £1,234.56
eur_0 €1,234
eur €1,234.56
id 1234

For numeric field types, id should only be used on numbers that have 16 digits or fewer. Beyond 16 digits, id may round results. For numbers with more than 16 digits, cast them as a string and use id on the string field type.

For percentage formats, Looker takes the underlying decimal value and multiplies it by 100 to get a percentage. The examples below start with the underlying value “0.123456”:

Name Example
percent_0 12%
percent_1 12.3%
percent_2 12.34%
percent_3 12.345%
percent_4 12.3456%
