Phpspreadsheet Bundle Laravel Package

Product Decisions This Supports

• Build vs. buy for export/import features. Spreadsheet export (XLSX/CSV/ODS) and bulk import are almost always table stakes, not differentiators. This bundle lets you ship them in days as a thin integration layer over PhpSpreadsheet rather than staffing a file-format engineering effort. Default PM position: buy/consume, redirect engineering capacity to the workflow around the file (templates, validation, error feedback, audit trail).
• Roadmap sequencing for reporting and data portability. Concretely unblocks: "Export this report to Excel," "Download my account data," finance/ops self-serve pulls, bulk record creation from customer-maintained spreadsheets, and scheduled report delivery. Use it to price and sequence those epics rather than debating the file-writing mechanics.
• Scope control on formatting fidelity. Because formatting, formulas, and multiple writers come from the underlying library, you can commit to XLSX with styling and formulas without a custom rendering project. Decide explicitly which fidelity tiers are in scope (raw data / styled / formula-bearing / charts) — the last tier is where cost and support burden jump.
• Support and ops cost modeling. PhpSpreadsheet is memory-hungry; large exports become an infrastructure and reliability story (timeouts, worker memory, queue design), not a library story. This drives decisions about async export jobs, file size limits, and whether to gate large exports behind a paid tier.
• Dependency and platform risk review. It's a glue package: low code volume, MIT, but 0 dependents and a concentrated maintainer base. That's an acceptable-risk input for adoption decisions and a standing item for your dependency review, not a blocker.
• Pricing/packaging input. Export limits (rows per export, scheduled exports, custom templates) are a natural, low-engineering lever for tier differentiation.

When to Consider This Package

Adopt when most of these hold:

• Your backend is Symfony (this bundle's only real reason to exist is DI wiring, config, and Symfony-idiomatic service access for PhpSpreadsheet).
• You need human-facing XLSX — styled reports, formulas, multiple sheets — not just machine-readable data dumps.
• Volumes are moderate (roughly thousands, not hundreds of thousands, of rows per file) and/or exports can run asynchronously with generous memory limits.
• You want the integration layer maintained by someone else rather than owning ~100–300 lines of container config plus a streamed-response factory.
• Your team is comfortable pinning versions and verifying the Symfony/PHP compatibility matrix at upgrade time.

Look elsewhere when:

• High-volume or memory-constrained export is the core need — evaluate a streaming writer (e.g., OpenSpout) or plain CSV; PhpSpreadsheet's object model is the bottleneck, and no bundle fixes that.
• You only need CSV — native fputcsv removes a dependency entirely.
• You're not on Symfony — use PhpSpreadsheet directly; the bundle adds nothing.
• You need enterprise-grade fidelity (pivot tables, complex chart replication, pixel-perfect template preservation) or BI-grade delivery — that's a reporting product or a dedicated service, not a library integration.
• You're processing untrusted uploads at scale — the parsing cost and zip-bomb/DoS surface argue for isolation (separate worker/service, hard limits) regardless of package choice.
• Maintenance signals look wrong for your risk tolerance: verify the current release actually targets your Symfony major and PHP version, check maintainer count and recent commit cadence, and confirm there's a credible path to fork the handful of files if it's abandoned.

Verification checklist before committing: Symfony/PHP version support, release cadence over the last 12 months, open-issue responsiveness, how temp files and caching are configured, and a spike measuring peak memory on your realistic worst-case file.

How to Pitch It (Stakeholders)

To executives: This is a small, MIT-licensed, low-lock-in Symfony integration that turns "Excel export/import" from a multi-sprint engineering project into a short integration task. It lets us ship a frequently requested capability — report exports, data portability, bulk import — in days, with no vendor spend and no proprietary format risk. The risk is contained: the bundle is glue code over a well-established open-source spreadsheet library, so worst case we replace a few hundred lines of configuration. Real cost drivers are operational (background jobs and memory limits for large exports), which we can size and gate deliberately. Recommendation: adopt for standard report exports, keep large-volume streaming on CSV/streaming writers, and re-review Symfony compatibility at each major upgrade.

To engineering: Use it as the wiring layer, not as an abstraction to build on. PhpSpreadsheet is the dependency that matters; the bundle just gives you autowired services and Symfony-idiomatic configuration. Keep spreadsheet logic behind a small internal interface so we can swap to a streaming writer for large exports without touching call sites. Run exports as queued jobs, set explicit row and memory ceilings, and validate every upload path with hard limits before parsing. Pin versions and add the Symfony-major upgrade to our dependency review.
