I will massively modify text file and drawings by logical criteria

Sometimes happens that a text or html or excel od drawing file has indesired values, in many ricurrencies: i can clean and substitute them all, avoiding you to enter manually hundreds of words. You have only to give me the logical criteria to individuate the parts to be correct, and the way to: for example, if you have a drawingwith many rcurrencies of a color code, i can massively correct conducing all individuated parts to the desidered colour. I can sonstitute all data with the ones you need, within the source data structure, in the way you need. I substitute word, numbers, formulas, each other, in large files
