Table Bundle Laravel Package

Product Decisions This Supports

• Build vs. buy on export/import. This package is a thin Laravel wrapper around Openspout, the PHP library that handles streaming CSV/XLSX/ODS read and write. The decision it informs is narrow: do we own spreadsheet serialization ourselves, or delegate to a maintained wrapper? For most product teams the answer is delegate — the hard part (format correctness, memory-efficient streaming, encoding edge cases) is Openspout's job, and a Laravel wrapper is glue you would otherwise write and maintain yourself.
• Scoping export features into a roadmap. Presence of a maintained package raises the default: "export to Excel" becomes a small, schedulable story rather than an epic. That changes where export lands relative to other backlog items — frequently it can ride along with an existing reporting or admin workstream instead of consuming its own sprint.
• Dependency and upgrade budget. The 0.16.0 release is a pure dependency-floor change: exports now require Openspout v5 and are explicitly incompatible with v4 and earlier. That is a one-line composer.json change for consumers, but it is a real calendar item — it must be sequenced against anything else in the codebase that touches Openspout, and against the team's appetite for churn on a pre-1.0 dependency.
• Version-pinning policy. A 0.x package shipping a breaking change mid-stream is the expected behaviour, not a governance failure. It does, however, argue for pinning to a minor and treating upgrades as deliberate, reviewed work rather than floating constraints in CI.
• Vendor and exit-risk review. Openspout is the substantive dependency here; the wrapper is replaceable in an afternoon. That reframes the risk conversation — the question to ask is not "will this package be abandoned?" but "is Openspout healthy, and do we have a path to calling it directly if we need to?"

When to Consider This Package

Adopt it when most of the following hold:

• You need user-facing or scheduled export of tabular data to CSV/XLSX in a Laravel application, and you want it to feel native to the framework rather than hand-rolling controllers and response types.
• Your export volume is modest and datasets are bounded — report downloads, admin exports, per-tenant data extracts. Streaming via Openspout means memory is less of a concern than with in-memory builders, but this is still not a data-warehouse extraction tool.
• Your team is comfortable pinning a pre-1.0 dependency and reviewing its changelog on upgrade. Expect breaking changes; they have already happened once and will happen again before 1.0.
• You are already on, or can move to, Openspout v5. This is now a hard precondition — the package's export path will not work against v4 or earlier.

Look elsewhere, or build directly on Openspout, when:

• You are pinned to Openspout v4. Another package in your stack, or a platform constraint, may hold you there. Until that clears, 0.16.0 is unusable and you should stay on 0.15.x with a documented reason and a revisit date.
• You need long-term API stability. A 0.x wrapper gives you no compatibility promise. If you are building a public API surface or a multi-year contract deliverable, either wrap this package behind your own abstraction or call Openspout directly so the churn stays one layer down.
• Your needs are genuinely simple. A single fixed CSV download does not justify a dependency. fputcsv and a streamed response are fine.
• Your needs are genuinely complex. Heavy formatting, formula evaluation, templated workbooks, pivot tables, or multi-hundred-megabyte files are Openspout-and-beyond territory, and you should be evaluating the underlying library's capabilities rather than a wrapper's.

How to Pitch It (Stakeholders)

For executives: We are evaluating a small, focused library that gives our Laravel applications the ability to export data to Excel and CSV without us writing and maintaining that code ourselves. The underlying engine is a mature, widely-used PHP library; this package is the thin integration layer. The commercial case is straightforward — it converts "export to Excel" from a multi-week build into a small piece of work, and it removes an entire category of bug (file format, encoding, memory blowups on large exports) from our maintenance burden. Cost is a Composer dependency and a small, periodic upgrade chore.

For engineering: This is a wrapper over Openspout. The newest release, 0.16.0, is a breaking change with exactly one consequence: the export path now requires Openspout v5 and no longer supports v4 or earlier. Migration for us is a constraint bump plus a regression pass on export endpoints — no application code changes expected. Two caveats to plan around. First, the package is pre-1.0, so breaking changes are the norm and we should pin to a minor and treat upgrades as reviewed work. Second, the real dependency risk sits with Openspout, not this wrapper — and the wrapper is thin enough that dropping to Openspout directly is a contained piece of work if we ever need to.

Recommended next step: confirm whether anything in our stack currently constrains us to Openspout v4. If nothing does, adopt 0.16.0 and pin it. If something does, hold at 0.15.x, log the constraint, and set a review date — do not adopt the new release half-way.
