decode json

i am doing
    %freeb =  %{$json->decode($fr_blob)};

and it is throwing warnings/messages like

unexpected end of string while parsing JSON string

for some rows it reads the data in a huge file line by line...

in perl can i do something that checks if the string is valid json and not process it if its invalid?
i want to eliminate these messages

how can i run json_decode on a string and if its bad json, then simply continue without barfing or throwing errors
Have you had a look at the following Article: Using Perl to preview in a Web Page and convert a JSON document into an Excel workbook ?


  # from file content
  local $/;
  open( my $fh, '<', "$sUploadDir/$sFilename" );
  my $json_text   = <$fh>;
  my $roPasedJson = JSON->new->utf8(1)->decode($json_text);
