It handles creation, reading, writing, and conversion of Excel spreadsheets in formats including .xls, .xlsx, .xlsb, .xlsm, and .ods. The library supports a wide range of operations: cell manipulation (merging, formatting, borders, fonts), worksheet management (add, copy, delete, hide), formulas and calculations, charts, images, comments, conditional formatting, and security features like encryption and digital signatures.\n\nThe package depends on plum-dispatch and is distributed as platform-specific compiled wheels for Windows, Linux (x64 and ARM64), and macOS (Intel and ARM64). It requires Python 3.7 or later. The library's main strength is its ability to convert Excel files to multiple formats (PDF, HTML, CSV, XML, TXT, SVG, XPS, ODS) and perform complex spreadsheet automation without external dependencies like LibreOffice or Microsoft Office.","worth_installing":"Yes, with conditions. Spire.XLS is actively maintained and offers comprehensive Excel functionality without Office dependencies, making it valuable for automation and conversion tasks. However, the unclear license status requires verification before production use\u2014confirm whether your use case (commercial, open-source, internal) is permitted under the proprietary terms. The compiled nature and platform-specific wheels mean you must match your OS and architecture exactly."},"id":"spire-xls","links":{"html":"https://skillfed.io/packages/spire-xls","md":"https://skillfed.io/packages/spire-xls.md","pypi":"https://pypi.org/project/spire-xls/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-17","license_spdx":null,"license_treatment":"unclear","name":"spire-xls","python_support":"supports_current","summary":"A 100% standalone Excel Python API for Processing Excel Files"},"popularity":{"monthly_downloads":107755,"position":12599,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"16.7.1"}
