feat(xlsx-pro): B1.3 — NeoReports.Xlsx.Pro multi-sheet workbook (commercial)

[thiagoluga]

The first paid "Pro" feature: a multi-sheet XLSX workbook that packs several views as worksheets in one .xlsx, built on the B1.2 sectioned-output hook.

API

using static NeoReports.Xlsx.Pro.Format;

builder
    .From(source)
    .Column(v => v.Id, "Id")
    .ToSections(XlsxWorkbook(o => o.AutoFilter()), s => s
        .Section("Approved", v => v.Where(x => x.Amount > 0))
        .Section("Rejected", v => v
            .Where(x => x.Amount <= 0)
            .Column(x => x.Id, "Id").Column(x => x.Customer, "Customer")));

→ one workbook with an Approved and a Rejected worksheet (each its own filter/columns) from a single source read.

Package NeoReports.Xlsx.Pro

• Format.XlsxWorkbook(...) → a SectionedOutputSpec for ToSections(...).
• XlsxWorkbookWriter : IReportSectionedWriter (ClosedXML): one worksheet per section, per-sheet header/auto-filter, sanitized+unique sheet names.
• Reuses the MIT cell semantics: extracted XlsxWriter's cell logic into a public XlsxCells.SetCell helper in NeoReports.Formats.Xlsx (no behavior change — the 4 Xlsx golden tests still pass), so the Pro writer emits identical native types/formats without duplication.

Commercial boundary (D27)

• Licensed PolyForm Small Business 1.0.0 (free under USD 1M revenue). LICENSE.txt carries the SPDX id + copyright + threshold + canonical URL, with a clear TODO to paste the verbatim body — I did not transcribe legally-binding text from a summary.
• IsPackable=false → excluded from the OSS NuGet release. Verified: dotnet pack NeoReports.sln produces all 8 OSS packages and no Pro nupkg.

Tests

Golden-file test opens the produced workbook and asserts the two worksheets, their headers, and the correctly-filtered rows/columns. Full solution builds clean.

Next / needs you (B1.4)

• Paste the verbatim PolyForm Small Business text into LICENSE.txt (standard doc from the canonical URL).
• Decide the Pro distribution (private NuGet feed? manual pack?) and whether CI packs it separately.

Also logged your concurrency/memory-under-load testing task in the PLAN backlog (+ a task chip).
