From messy spreadsheets to polished, auto-generated stories — how I used Python to interchange hours of handbook Excel work with a single script
If you happen to’ve ever been buried in Excel sheets — copying, pasting, vlookuping, and questioning if that is actually your job — then this text is for you.
I used to spend an hour each Monday producing weekly stories from a tangle of uncooked Excel information. Then I discovered the holy grail: Python + pandas + openpyxl + matplotlib. Now, my stories generate themselves whereas I make espresso.
Right here’s precisely how I constructed a totally automated Excel reporting system in Python.
I used to be handed a weekly job:
Open three Excel information, extract the most recent rows, apply calculations, format them, and ship a PDF report.
It took an hour every time. Right here’s what I used to be coping with:
- A number of Excel information (Gross sales, Stock, Bills)
- Blended codecs, merged cells, bizarre headers
- Charts and abstract tables
- Copy-pasting outcomes right into a PowerPoint deck or PDF
