Description

The Lookup From Table Component can be used to convert from different tables that parsed as a CSV.

Credentials

CSV Table: The CSV is entered on the Credentials page as a list of separated items. Any delimiter is supported. The CSV will be parsed using the first row as a header for each column below it. The CSV must be able to be interpreted as a rectangle, i.e. it cannot be missing values.

For example,

English,Abbreviated,German
male,M,männlich
female,F,weiblich
other,O,divers
unknown,U,unbekannt

Will parse as

English	Abbreviated	German
male	M	männlich
female	F	weiblich
other	O	divers
unknown	U	unbekannt

and

English,Abbreviated,German
male,M,männlich
,F,weiblich
other,,
unknown,U,unbekannt

Will parse correctly as

English	Abbreviated	German
male	M	männlich
	F	weiblich
other
unknown	U	unbekannt

(though this may not be useful), but

English,Abbreviated,German
male,M,männlich
F,weiblich
other
unknown,U,unbekannt

will provide a failed result.

The CSV can only be a maximum of 5kB.

Triggers

Actions

Lookup From Table

The lookup from table action takes a table to lookup from, a table to translate to, and an input value to translate. It returns an object in the form {result: value} where the value is the result of the table lookup, if it exists:

Configuration Fields

Input Configuration

• Emit empty object on unsuccessful lookup: if selected, an empty object {} will be emitted given an unsuccessful lookup where nothing is found. If not selected, an error will be thrown on unsuccessful lookup
• From this column: the column to translate from
• To this column: the column to translate to
• Duplicates behavior: How to handle cases when found several records in selected From this column in provided table, options:
  • Emit all mach individually - Will emit each record as separate message
  • Emit all mach as Array - Will emit all founded records as array of strings
  • Emit first found - Will emit first founded record
  • Throw an error (Default) - By default error will be thrown

Expected input metadata

• Input: the value to translate. Should be selected from the list of available values under Values

Expected output metadata

• if lookup is successful, an object of the type {"result": "value"} will be emitted
• if lookup is unsuccessful and emitting empty object, {} will be emitted
• if lookup is unsuccessful and not emitting an empty object, and error will be emitted

Additional Info

• Any elements of the CSV that contain the delimiter in them should be wrapped in "double quotes". Any elements of the CSV that contain the delimiter and also quotations should have the quotes backspaced.

e.g.

Full Name,First,Last
"Bond,James",James,Bond
"Johnson, Dwayne \"The Rock\"",Dwayne,Johnson

• If you want to mark an element as a string (e.g. "5" or "Some text inside a single element"), you must use ", not ', because ' is considered as an additional character. So in this case: 2 is the same as "2", but '2' would be equal to "'2'".

Known Limitations

• the CSV has a max size of 5kB
• the CSV must be able to be parsed as a rectangle
