Lyo.Xlsx.Models

Interfaces and value types for the Lyo XLSX stack. Defines the contract implemented by Lyo.Xlsx so consumers can depend on IXlsxService / IXlsxReader / IXlsxWriter without pulling in ClosedXML or ExcelDataReader directly.

Interfaces

  • IXlsxService — façade that exposes Writer, Reader, and the full read / write / convert / HTML / batch / multi-sheet surface.
  • IXlsxWriter — write enumerables, selected PropertyInfo columns, custom column-name dictionaries, formatter delegates, multi-sheet workbooks (IReadOnlyDictionary<string, IEnumerable<T>>), row/column dictionaries (useFooterRow peels last row as bold footer), and Lyo.DataTable.Models.DataTable snapshots (always appends Footer + formats at row -2 when present) to file, Stream, or byte array. CreateDocumentWriter opens an incremental multi-sheet session. Sync overloads work on all targets; async, IAsyncEnumerable<T> export, custom-header, and formatter overloads are gated on !NETSTANDARD2_0.
  • IXlsxReader — parse worksheets of files, streams, and byte arrays as a row/column dictionary or Lyo.DataTable.Models.DataTable (wrapped in Result<T>; useFooterRow peels the last body row into Footer). ParseXlsx*AsDataTable is values + merge spans only; ParseXlsx*AsDataTableWithFormatting also fills the table's sparse format map. Sheet control via ListSheetNames, by-name / by-index overloads, and ParseXlsx*AsAllSheets / …WithFormatting. On net10.0, forward-only IAsyncEnumerable streaming (ParseXlsx*RowsStreamingAsync, typed ParseXlsx*StreamingAsync) uses ExcelDataReader without materializing the sheet. Async overloads are gated on !NETSTANDARD2_0.
  • IXlsxDocumentWriter — disposable incremental writing session: each AddSheet / AddSheetFromDataTable / AddSheetFromDictionary call streams one worksheet; dispose finalizes the workbook. On net10.0, AddSheetAsync accepts IAsyncEnumerable<T>. Sheet names are unique per session (case-insensitive).

Models

  • XlsxCellValue — sealed record with textual Value plus merge spans (ColSpan, RowSpan). Formatting uses Lyo.DataTable.Models.DataTableCellFormat on the DataTable map, not this type.
  • XlsxOptions — includes nested DataTablePoolingOptions (PoolValues, PoolFormats, PoolingCellThreshold, default 512).
  • XlsxCellValueExtensions — maps XlsxCellValue to a thin IDataTableCell.
  • XlsxExportResult / XlsxParseResult — result envelopes used by the higher-level helpers.

Multi-targeting

Targets netstandard2.0;net10.0. Async, custom-header, and formatter overloads are wrapped in #if !NETSTANDARD2_0 and are only visible on the net10.0 TFM.
