Open-Source biblioteka Pythona dla arkuszy Excel

Aspose.Cells FOSS for Python to darmowa, otwarto‑źródłowa biblioteka do pracy z plikami arkuszy kalkulacyjnych w aplikacjach Python. Zainstaluj ją jednym poleceniem pip install aspose-cells-foss i rozpocznij tworzenie skoroszytów, odczytywanie komórek, stosowanie stylów, budowanie wykresów oraz eksport do XLSX, CSV, TSV, Markdown lub JSON, wszystko bez wymogu posiadania Microsoft Excel ani żadnych zależności Office.

Biblioteka udostępnia czyste, Pythoniczne API zbudowane wokół Workbook, Worksheet, Cells i Cell, znanych obiektów, które każdy programista arkuszy kalkulacyjnych rozpoznaje. Czytaj i zapisuj komórki używając notacji nawiasowej (ws.cells["A1"].value = "Hello"), stylizuj je przy pomocy obiektów Font i Fill, a także twórz wykresy kolumnowe lub liniowe, korzystając z dedykowanych metod add_bar() i add_line() dostępnych w ws.charts.

Ponieważ biblioteka nie ma zależności od natywnych bibliotek Office, działa identycznie na systemach Windows, Linux i macOS w środowiskach CI, kontenerach Docker oraz w środowiskach serverless. Pakiet markitdown-aspose-cells-plugin rozszerza bibliotekę Microsoft MarkItDown o obsługę XLSX, umożliwiając pełny eksport skoroszytu do Markdown za pomocą jednego wywołania.

Read and Write Excel Files

  • XLSX: Open and save workbooks with full round-trip fidelity.
  • Cell access: Read and write values with ws.cells["A1"] bracket notation.
  • Formulas: Write formula strings stored verbatim in XLSX — evaluated by Excel or LibreOffice on open, not by the library at save time.
  • Multiple export formats: Export to CSV, TSV, Markdown, and JSON.
  • Round-trip safe: Unknown XML parts are preserved verbatim on re-save.

Where Aspose.Cells FOSS Can Be Used

  • Data pipelines: Export database query results directly to XLSX or CSV.
  • Report generation: Build styled, branded Excel reports without Office.
  • Documentation: Convert spreadsheets to Markdown via the MarkItDown plugin.
  • ETL workflows: Read input sheets, transform data, and write output workbooks.
  • CI/CD automation: Generate test-result spreadsheets inside Docker containers.

Styling, Charts, and Security

  • Font and fill: Apply bold, italic, font size, foreground and background colors.
  • Number formats: Set date, currency, and custom number formats per cell.
  • Charts: Build bar, line, pie, scatter, area, and combo charts.
  • AES encryption: Protect workbooks with a password parameter in one line.
  • MarkItDown plugin: markitdown-aspose-cells-plugin adds XLSX export to MarkItDown.

Developer Experience

Aspose.Cells FOSS is installable with a single pip install aspose-cells-foss command. There are no native Office libraries or system packages to install. The library runs on any Python 3.7+ environment without compilation steps.

The API is intentionally small: Workbook, Worksheet, Cells, Cell, Font, Fill, and Chart cover the vast majority of real-world use cases. The codebase is MIT-licensed, hosted on GitHub, and accepts bug reports and pull requests.

Create a Workbook and Write Cells

Install with pip, then create a Workbook, access the first Worksheet, and write values directly to cells using bracket notation. The example also shows how to bold the header row by modifying the cell style before saving.

pip install aspose-cells-foss

from aspose.cells_foss import Workbook

wb = Workbook()
ws = wb.worksheets[0]

# Write values
ws.cells["A1"].value = "Product"
ws.cells["B1"].value = "Revenue"
ws.cells["A2"].value = "Widget"
ws.cells["B2"].value = 42000

# Bold the header row
for col in ["A1", "B1"]:
    style = ws.cells[col].get_style()
    style.font.bold = True
    ws.cells[col].apply_style(style)

wb.save("report.xlsx")

Build a Chart and Export to Multiple Formats

Open the workbook saved above, add a bar chart over a range of rows, then call save() three times with different file extensions — XLSX, Markdown, and CSV — without changing any other code.

from aspose.cells_foss import Workbook

wb = Workbook("report.xlsx")
ws = wb.worksheets[0]

# Add a bar chart over rows 2-10
chart = ws.charts.add_bar(12, 0, 25, 6)
chart.n_series.add("B2:B10", True)
chart.title = "Revenue by Product"

wb.save("report_with_chart.xlsx")

# Export the same workbook to Markdown
wb.save("report.md")

# Or export to CSV
wb.save("report.csv")
