FAQ
Do I need Python installed on my computer to run the script?
It depends on the package selected. For Basic fixes, I deliver the processed data directly. For Standard and Premium script packages, I can give instructions on how to install Python/pip or package the script into an executable (.exe) upon request so you can run it effortlessly with a single clic
What data formats and file types can your scripts handle?
My scripts primarily process .csv, .xlsx, .xls, and unstructured text/log files. If you have custom database dumps or JSON exports, feel free to message me before ordering to confirm compatibility.
Will I receive the full source code with my delivery?
Yes! For all script-building packages, you receive clean, fully commented .py source code along with execution notes so you retain 100% ownership and control over the automation pipeline.
