I will write a python script to batch process or convert your files

Need a python script that does one job properly and does not fall over on file number 400?

I write command line tools that handle files in bulk - convert, rename, extract, split, merge, validate, reorganise, clean up.

Not a notebook and not a snippet. A real tool with proper arguments, useful error messages, and sane behaviour when the input is messy.

What you get:

A python script, or a packaged .exe so nothing needs installing

Command line options instead of hardcoded paths you have to edit

Batch processing that survives thousands of files

Clear errors that say what is wrong, not a stack trace

Commented source code you own outright

A short usage guide written for a human

I am comfortable with awkward input: mixed encodings, malformed rows, undocumented binary formats, deeply nested folders, and files that are technically invalid but still have to be read.

Tell me what your files look like and what you need out of them. Send one sample and I will confirm the scope before you order.
