SQL Query to split string and replace characters in SQL Server

 i written one table valued function to split string

create FUNCTION [dbo].[StringSplit](@input NVARCHAR(MAX), @delimiter CHAR(1)=',')
RETURNS @returnTable TABLE(item NVARCHAR(100)) AS
BEGIN
IF @input IS NULL RETURN;
DECLARE @currentStartIndex INT, @currentEndIndex INT,@length INT;
SET @length=LEN(@input);
SET @currentStartIndex=1;
SET @currentEndIndex=CHARINDEX(@delimiter,@input,@currentStartIndex);
WHILE (@currentEndIndex<>0)
BEGIN
INSERT INTO @returnTable VALUES (LTRIM(SUBSTRING(@input, @currentStartIndex, @currentEndIndex-@currentStartIndex)))
SET @currentStartIndex=@currentEndIndex+1;
SET @currentEndIndex=CHARINDEX(@delimiter,@input,@currentStartIndex);
END
IF (@currentStartIndex <= @length)
INSERT INTO @returnTable
VALUES (LTRIM(SUBSTRING(@input, @currentStartIndex, @length-@currentStartIndex+1)));
RETURN;
END;

i am using above function in below select query

DECLARE @testString VARCHAR(100)
SET @testString = replace(replace('{"Product":"algoda","Product2":"Nao","Product3":"Nao1"}','{',''),'}','')
