Practical Python tutorials for Excel automation and reporting workflows
Explore production-focused guides that turn recurring Excel reporting into maintainable, automated workflows — pandas and openpyxl for the data, xlsxwriter for the output, SQL and API sources upstream, and scheduling, delivery, testing and packaging around the whole job. Every file format, date and timezone problem you will meet is covered too.
Quick snapshot
- Reading, writing, formulas, validation and large-file techniques in one place
- openpyxl, pandas, xlsxwriter and xlwings — with guidance on which to reach for
- Every format you will meet: .xlsx, .xlsm, legacy .xls, .ods and CSV
- Dates, timezones and period grouping handled properly, not guessed at
- SQL and API sources in, formatted workbooks out, on a schedule
- Delivery to S3, SharePoint, Drive or a share — with protection and PDF export
- Testing, configuration and packaging so somebody else can run the job
