プロジェクトの歴史

The GitHub repository was created on 2012-06-30, and release 0.3 was published on 2013-12-13. The README describes it as a CLI for diffing Excel and ODS workbooks, built on Apache POI and OdfToolkit.

採用の歴史

ExcelCompare found a practical niche among developers who need spreadsheet diffs in shells, scripts, and version-control workflows. The README explicitly documents macOS installation via Homebrew and notes packaged shell and batch scripts.

The project has remained recognizable enough for Homebrew packaging and GitHub issue-based maintenance, even though the core use case is narrow.

使われ方

The excel_cmp command compares two workbook files and exits 0 when workbooks match or 1 when they differ. It reports differing and extra cells, supports xls, xlsx, xlsm, and ods files, and can ignore sheets, rows, columns, or cell ranges independently for each input.

The README also documents unified-diff output and using /dev/null or Windows NUL as an empty file, which makes the tool suitable for git diff-style workflows over spreadsheets.

パッケージ好きにとっての重要性

ExcelCompare packages a messy office-document problem into a scriptable Unix-style CLI with deterministic exit codes. That makes it useful in CI and review workflows where binary spreadsheet files otherwise resist normal diff tools.
