Flowthru.Extensions.Excel

Read Flowthru Catalog Items from Excel workbooks. Adds the Excel format to the Catalog builder, so any Item backed by a row sequence loads from a .xlsx worksheet with a one-line declaration. Excel here is read-only — it's for ingesting spreadsheets someone handed you, not for emitting them; an Excel-backed Item reports that it can't be written, and a Flow that tries to save to one fails fast before it touches the workbook.

coverage

Mental model

Storage in Flowthru is three independent axes: format (how bytes serialize) × medium (where bytes live) × container (the in-memory shape). This package supplies one format — Excel. Bring the spreadsheet mental model: a workbook holds named sheets, a sheet has a header row, and each row below it is a record. You name the sheet to read; Flowthru maps each row onto your schema. It doesn't care where the .xlsx lives (that's the medium's job), only how a row maps to your typed schema.

Install

dotnet add package Flowthru.Extensions.Excel

Declare an Excel-backed Item in your Catalog. Unlike the other formats, Excel requires a sheet name — a workbook can hold many sheets, so you say which one:

public IItem<IEnumerable<ShuttleSchema>> Shuttles =>
    CreateItem(() => Item.Of<IEnumerable<ShuttleSchema>>("Shuttles")
        .Excel()
        .AtPath($"{_basePath}/Data/_01_Raw/shuttles.xlsx")
        .WithSheet("Sheet1")
        .Build());

If your nullable columns use placeholder strings for blanks, declare them with .WithNullValues(...) so they parse as null rather than literal text.
