In offices it is mostly used for data work: totalling, combining and cleaning exports that would otherwise be done by hand in a spreadsheet, usually with the free pandas library. Last updated October 24, 2026 [Take the free module →](https://learn.ynteractive.com/courses/python-for-spreadsheet-work/1)Module 1 of the free [Python for Spreadsheet Work Jump Start](https://learn.ynteractive.com/courses/python-for-spreadsheet-work) course, about 12 minutes. No account needed. Updated October 24, 2026 · By [Robert Breen](https://learn.ynteractive.com/content/about) ## Why it matters for a small business Spreadsheet work that repeats every week or month (total the export, combine the monthly files, fix the names, remove the duplicates) is exactly what a few lines of Python do well. The lines are written once and run again on the next export in seconds, with the same result every time. You do not need to install anything to start. Google Colab runs Python in a browser tab for free, in notebooks of small cells, and saves them to Google Drive. Each cell shows its answer straight under it, so mistakes show up at once. Python is also the language most AI tools write when you ask them to analyse a file, so knowing the basics lets you read, check and adjust that code instead of trusting it blindly. A good first goal is one job you already do by hand every month. Write it as a notebook once, keep it in Drive, and next month change only the file name. The time saved grows with every run, and the notebook doubles as a written record of exactly how the numbers were made. ## In a real lesson: Python: Total a Sales Export by Customer in Google Colab In the free [Python sales report lesson](https://learn.ynteractive.com/content/python-sales-report), Priya (made up) types six orders into a Colab notebook as two lists and turns them into a pandas table. One line, sales['amount'].sum(), gives the quarter's $8,180. Two more, a groupby and a sort, rank the customers: Cobalt Legal $3,170, Maple Dental $2,230, Northside Realty $2,140 and Harbor Accounting $640.

Python runs anywhere, handles much larger files and is the language most data and AI tools speak. ## Tips - Start in Google Colab: nothing to install, and every notebook saves to your Drive. - Press Shift+Enter to run a cell; Enter only adds a new line inside it. ## Related terms [pandas (Python)](https://learn.ynteractive.com/content/glossary/pandas) · [CSV](https://learn.ynteractive.com/content/glossary/csv) ## More Data, Sheets and Gmail terms [Rows](https://learn.ynteractive.com/content/glossary/rows-spreadsheet) · [Searchable PDF](https://learn.ynteractive.com/content/glossary/searchable-pdf) · [SQL](https://learn.ynteractive.com/content/glossary/sql) · [SUMIF](https://learn.ynteractive.com/content/glossary/sumif) ## Where you use it: free lessons - [Python: Total a Sales Export by Customer in Google Colab](https://learn.ynteractive.com/content/python-sales-report) (Google Colab, 12 min) - [Python: Combine Monthly Sales Exports into One Quarter](https://learn.ynteractive.com/content/python-combine-exports) (Google Colab, 12 min) - [Python: Clean a Messy Invoice Export Before You Total It](https://learn.ynteractive.com/content/python-clean-invoice-export) (Google Colab, 12 min) - [Analyze a Donor Gift Export with ChatGPT: Board-Ready Giving Numbers for a Nonprofit](https://learn.ynteractive.com/content/chatgpt-analyze-donor-gift-export-nonprofit) (ChatGPT, 11 min) ## Watch it in a free lesson: Analyze a Spreadsheet with ChatGPT: Upload a CSV, Get a Chart and Three Takeaways ### Analyze a Spreadsheet: video walkthrough Full walkthrough · 3:04 · with captions Upload a CSV of sales to ChatGPT, have it check the data first, ask your questions, get a chart you can download, and finish with the three takeaways that matter.

Most office tasks need fewer than ten lines. **Can Python read my Excel or CSV exports?** Yes. pandas reads CSV files with pd.read_csv and Excel files with pd.read_excel.
