Mapping Tables

Mapping tables serve as a dictionary between source value (Match, left column) and target value (Value, right column).

They work similarly to a V-Lookup: if a value matches the left column the corresponding value of the right column is inserted into the field. You can also include Regular Expressions in the match column, as described below.

EXAMPLE 1 - Manual Mapping

1. Navigate to Enrich. 
   
2. a. Go to "Mapping Tables";
   b. Click "+Add".
   
   
3. Click "+Add another entry" and begin manually populating the mapping table, where "Match" equals the value to search for in the source data, and "Value" equals the new value that will replace it.
   
   

   Example Input 1

   dim_A	metric_1
   UK	111
   DE	222
   US	333

   Example Output 1

   dim_A	New_Column	metric_1
   UK	United Kingdom	111
   DE	Germany	222
   US	United States	333

EXAMPLE 2 - Using Regex Expressions

1. Put '/' at the start and end of the entry to convert it into a regular expression. In the table below anything starting with 'DE_' would be translated to 'Germany'.

   

   Example Input 2

   dim_A	metric_1
   DE_Munich	111
   DE_Berlin	222
   DE_Frankfurt	333

   Example Output 2

   dim_A	New_Column	metric_1
   DE_Munich	Germany	111
   DE_Berlin	Germany	222
   DE_Frankfurt	Germany	333

Ticking Ignore Case will find matches regardless of upper- or lower-case characters.

USING REGEX EXPRESSIONS IN MAPPING TABLES

Within mapping tables, the following entries can be used on the left-hand side of the table:

• /.*adwords.*/ -> everything that contains "adwords"
• /adwords.*/ -> everything that starts with "adwords"
• /.*adwords/ -> everything that ends with "adwords"
• /(A|a)dwords/ -> everything that is exactly "Adwords" or "adwords"
• /.*(a|A)dwords.*/ -> combination of multiple is possible

We suggest you use regex101 or a similar regular expression tool to test your regular expressions.

Please note that mapping entries are checked in order: top-down.
