●●SolidShip ItSolve My Problem
40x faster than openpyxl with zero-copy Arrow integration for DataFrame workflows.
Strengths
- •Benchmarks show 5-40x speedup over established Python Excel libraries with real numbers.
- •Zero-copy Arrow integration eliminates intermediate conversions for Polars and Pandas.
- •Streaming XML generation keeps memory usage near zero even at million-row scale.
Weaknesses
- •Rust-backed Python speedup is a known pattern — not architecturally novel.
- •xlsxwriter and polars.write_excel already serve this category adequately.
