Comparison: Character Transposition Match

The Character Transposition Match comparison matches strings/string arrays where character transpositions have occurred. For example, when comparing the values 'Michael' and 'Micheal', a single transposition will be counted, so the two values will match if the Maximum allows transpositions option is set to 1 or higher.

Option	Type	Default Value
Match No Data pairs?	Yes/No	No
Ignore case?	Yes/No	Yes
Starts with?	Yes/No	Yes
Maximum allowed transpositions	Value

Example

In this example, the Character Match Percentage comparison is used to match company names. The following options are specified:

Match No Data pairs? = No
Ignore case? = Yes
Starts with? = Yes
