How to pass String to Bulk instead of file?

I used the bulk insert command to convert the CSV file table. Currently, I saved the CSV file as VarBinary value in sql server. Now I can get the data from the Varbinary file by specifying it in Varchar using the CAST and CONVERT functions. But now I have a problem, I cannot convert this Varchar string containing csv content to a table using bulk insert. Can someone help me My sample code is below:

--@String contains varchar value of CSV file content.  
SET @sql = 'BULK INSERT TempCsv
FROM  ''' + @String  + '''
WITH
(
    FIRSTROW = 2,
    FIELDTERMINATOR = '','',  
    ROWTERMINATOR = ''\n'',   
    TABLOCK
)'

Please help me. Is there a way or alternative to insert data from a csv row into a table.

EDIT: allow multiple char delimiters

This is how I solved it. It includes:

  • - (xftSplit) (char (10))
  • (fSubstrNth) n-
  • (fPatIndexMulti) n-
  • () Right
  • , - , SQL ( , SELECT )

BEGIN

  While len(@Texto)>0 BEGIN
    SET @Pos = Patindex('%'+@Splitter+'%',@Texto)

    IF @Pos > 0 BEGIN
      INSERT INTO @Lista
      SELECT left(@Texto, @Pos-1)

      SET @Texto = right(@Texto, len(@Texto)-@Pos)

    ELSE BEGIN
