Works just like FileMaker's Substitute( ) function, but case is ignored.

Sample Input:
SubstituteCaseInsensitive ( "abAbaBAB123a4b7aB" ; "aB" ; "zz" )
Sample Output:
zzzzzzzz123a4b7zz


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

Returns a text string with every occurrence of searchString in text replaced by replaceString in text. Works just like FileMaker's Substitute( ) function, but case is ignored.

Good for standardizing the case of a string across multiple records, where the case wasn't previously controlled, such as migrating hand-typed status or category fields from one system to another. Also useful for removing all instances of a string across multiple records, where that string could have variable case.

Example:

"I Do noT liKe them in a box.
I Do Not Like them with a fox
i do nOt likE them in a house
i do not like them with a mouse"

will be changed to:

"I do not like them in a box.
I do not like them with a fox
I do not like them in a house
I do not like them with a mouse"

with one call of the SubstituteCaseInsensitive( ) function, where the call is SubstituteCaseInsensitive( theFirstExampleParagraphAbove, "I do not like" ; "I do not like" )

Will replace up to the 1st 10,000 instances of the searchString (based on FileMaker's recursive function call stack limit).

It goes without saying that this function doesn't support the multiple-search-and-replace bracket notation that the native Substitute( ) function supports, as FileMaker doesn't provide the ability to define optional parameters in a custom function.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Discuss:

It'd be great if this followed FileMakers native syntax allowing for multiple pairs of substitute.

SubstituteCaseInsensitive(text;[“a”;“A”];[“b”;“B”])
