Position WolfXL as the fastest credible path for existing Python Excel workflows by focusing on one wedge:
- openpyxl-compatible API
- reproducible performance + fidelity benchmarks
- low migration friction
- Publish reproducible benchmark methodology and raw results.
- Make migration friction near-zero (3-minute quickstart + import-swap examples).
- Recruit 5-10 design partners and produce outcome-backed case studies.
- Launch across developer channels with evidence-first messaging.
For developer tools, trust beats reach. Adoption grows when claims are reproducible and switching risk is low.
- Headline: Make Excel automation faster without rewriting your code.
- Subheadline: WolfXL is an openpyxl-compatible engine backed by Rust, built for high-fidelity Excel reads/writes with reproducible benchmarks.
- CTA 1: Get Started in 3 Minutes
- CTA 2: See Reproducible Benchmarks
- Openpyxl-compatible API
- Reproducible benchmark suite
- Public fidelity + performance tracking
- Swap imports.
- Run your workflow (read/write/modify).
- Measure impact on your files.
- No black-box claims (methodology + commands + fixtures published)
- Known limitations documented
- Compatibility path for legacy

pip install wolfxl# before
from openpyxl import load_workbook
# after
from wolfxl import load_workbookWe just launched WolfXL: a Rust-backed, openpyxl-compatible Excel engine focused on speed + fidelity.
What it is:
- Drop-in style API for common openpyxl workflows
- Reproducible benchmark methodology (not cherry-picked screenshots)
- Public results + known limitations
Why we built it:
Excel automation at scale can get painfully slow, and rewrites are expensive.
WolfXL aims to reduce runtime without forcing teams to rebuild pipeline logic.

Show HN: WolfXL — openpyxl-compatible Excel I/O with reproducible fidelity + performance benchmarks
I built WolfXL to speed up Python Excel workloads without requiring a new programming model.
What’s different:
- API designed to feel familiar for openpyxl users
- Benchmark results are reproducible (fixtures, commands, hardware context disclosed)
- Compatibility transition path included
I’d love feedback on:
1) Real-world files where performance regresses
2) Fidelity edge cases we should prioritize
3) Missing migration docs/examples that would block adoption

Subject: Can we benchmark your Excel pipeline with WolfXL? (hands-on support)
Hey [Name] — I’m building WolfXL, a faster openpyxl-compatible Excel engine.
I’m onboarding a small set of design partners and can help migrate one real workflow end-to-end.
Goal: measurable runtime improvement without changing your business logic.
What I’m asking:
- 1 representative workbook/pipeline
- 30–45 min kickoff
- feedback on migration friction + correctness
What you get:
- before/after benchmark report on your workload
- direct support on migration issues
- priority fixes for blockers you hit
If useful, I can send a 1-page technical brief and proposed test plan.
