Basically, the Cell Replacer is the node you’d want to use, i think It requires the dictionary you provided with your table instead of a file like the “String Replace (dictionary)”.
Anyway my solution need to use String Replace with Dictionary because I have many word to replace . On another way, I can use Joiner node to mapping word but I think it hard workforce.
Rer on your issue. I had seen your text file maybe problem to machine readable because Arabia language read/wreite right to left but many language usual is left to right. so may computing read has corrupt error.
