Written in Rust, it is designed\nfor speed, safety, and ease of integration into CI/CD pipelines.\n\nThe suite consists of three specialized CLI tools:\n\n- **sheetlint**: Advanced spreadsheet linter with hierarchical rule enforcement.\n- **sheetstats**: Detailed statistics and dependency analysis for workbooks.\n- **sheetcli**: General-purpose spreadsheet operations (convert, modify,\n  repair).\n\n## Installation\n\n### From Source\n\nRequires [Rust](https://www.rust-lang.org/tools/install) (latest stable).\n\n```bash\n# Clone the repository\ngit clone https://github.com/cosmoscalibur/sheetrs.git\ncd sheetrs\n\n# Install all tools\ncargo install --path sheetlint\ncargo install --path sheetstats\ncargo install --path sheetcli\n```\n\n## Tools Overview\n\n### 1. sheetlint\n\nA comprehensive linter for detecting errors, security issues, performance\nbottlenecks, and style violations.\n\n**Features:**\n\n- **Hierarchical Reporting**: Violations grouped by file → sheet → cell.\n- **Configurable**: TOML-based configuration with global and per-sheet\n  overrides.\n- **Formats**: Support for JSON and text output.\n\n**Usage:**\n\n```bash\n# Lint a file\nsheetlint workbook.xlsx\n\n# Lint with custom config\nsheetlint workbook.xlsx --config sheetlint.toml\n\n# CI/CD mode (JSON output) (:warning: experimental/unstable)\nsheetlint workbook.xlsx --format json \u003e report.json\n```\n\n**Key Rules:**\n\n- `ERR001`: Error cells (#DIV/0!, etc.)\n- `SEC001`: External workbook references\n- `PERF006`: Excessive conditional formatting\n- `UX002`: Inconsistent date formats\n- `SM001`: Excessive sheet counts\n\n### 2. sheetstats\n\nProvides deep insights into workbook structure, complexity, and dependencies.\n\n**Features:**\n\n- **General Stats**: Counts of sheets, cells, formulas, values.\n- **Dependencies**: Builds a graph of inter-sheet dependencies (upcoming).\n\n**Usage:**\n\n```bash\n# Get general stats\nsheetstats workbook.xlsx\n```\n\n### 3. sheetcli\n\nA swiss-army knife for spreadsheet manipulation.\n\n**Features:**\n\n- **Modification**: Remove sheets, delete named ranges.\n\n**Usage:**\n\n```bash\n# Remove sensitive sheets and save to new file\nsheetcli input.xlsx --remove-sheets \"Secrets\" \"Admin\" --output cleaned.xlsx\n\n# Remove named ranges\nsheetcli input.xlsx --remove-ranges \"OldRange\" --output cleaned.xlsx\n```\n\n## Roadmap\n\n- **Error Propagation Tracing**: Future versions may trace only the root cause\n  error cell rather than reporting all affected cells.\n- **Python Bindings**: PyO3 bindings for direct integration with Python data\n  workflows.\n- **Windows \u0026 WASM**: Windows support is likely functional but untested. WASM\n  target for browser-based linting is planned.\n- **Performance Review**: Continuous optimization for large workbooks (\u003e1M\n  cells).\n\n## Architecture\n\nSee [ARCHITECTURE.md](ARCHITECTURE.md) for a detailed technical breakdown of the\n`sheetrs` library and the CLI tool implementations.\n\n## License\n\nMIT\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcosmoscalibur%2Fsheetrs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcosmoscalibur%2Fsheetrs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcosmoscalibur%2Fsheetrs/lists"}
