DefterError, readNdjsonStream, NdjsonStreamWriter.write()/end(), the boolean headerRow on toHtml/toMarkdown, OdsStreamRow, and the StreamWriterOptions alias are gone; each had a replacement since v1.0. The raw-XML part parsers (parseChart, parsePivotTable, parseSlicers, parseThemeColors, …) are exported from hucre/ooxml only. A name on two entry points carried two stability promises. cloneChart, addChart and getCharts stay on the root: they take a Chart, not an XML string. Starts the "Migrating to v2" section of MIGRATION.md. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UU3YfLMdFvTcXyVFyXb28e
ReadOptions was one interface for four readers with a table in its doc
comment saying which reader ignored what; readXls(bytes, { password })
compiled and did nothing. Each reader now takes its own type —
XlsxReadOptions, OdsReadOptions, XlsbReadOptions, XlsReadOptions — over
a shared ReadOptionsBase, and the type is the table. ReadOptions stays
as the type read() takes, an alias of the widest.
A new test reads each reader's source and fails when a declared field is
never looked at. Doing that showed readXlsb honouring no maxTotalCells at
all — the only reader without a bounding-box ceiling — so it has one now.

Fonts, fills and borders took Color; a colour scale's stops, a data bar's fill and a sparkline's series colour took a hex string. The string could hold RGB and nothing else, so a theme colour — what Excel writes when a colour is picked from the palette — read back as "" and was written back as rgb="" (worksheet.ts read only the rgb attribute at those three sites). All three are Color now and go through the same parser and serializer fonts use.

Their reason to exist was that structured clone "does NOT handle Map". It does — Map, Date and Uint8Array are in the algorithm in every runtime hucre supports — so the pair converted a Workbook into a shape postMessage could already carry. 504 lines, and a register test that made every new model field a field to add here too. The register now asserts the promise that replaces them: a full Workbook survives structuredClone. A class instance added to the model would come back a bare object there and fail.

The reader put an error cell into rows as the string "#N/A"; the writer
wrote any string spelling an error token as t="e". So the text "#N/A"
typed into a cell became an error on write, and an error read from one
file was indistinguishable from the same text in another.
CellValue gains { error: string } — a plain object like the rest of the
model, built with cellError() and recognised with isCellError(). Every
reader produces it, including ODS, where LibreOffice marks an error cell
calcext:value-type="error"; the ODS writers now emit that mark too, so
errors round-trip through ODS. The XLSX writers write t="e" for a
CellError and for nothing else. Text formats write the token, as before.
sortRows orders errors after booleans, as Excel does; findCells and
replaceCells match one by its token.

Sheet.rows has been documented as a dense rectangle since v1 and readXlsx delivered one; readOds, fromHtml and the CSV path of read() returned [] for an empty row and left a short line short, so one sheet read three ways had three shapes, and PARITY.md carried a section admitting it. They pad to the sheet's width now, through one helper. parseCsv keeps the file's lines as they are — it is a grid function, not a Sheet reader — and the streaming readers still skip empty rows, since they cannot know the width before the last row. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UU3YfLMdFvTcXyVFyXb28e
Five stream*Rows readers yielded four shapes: { index, values } from
XLSX and ODS (with an optional sheetIndex on ODS), a bare array from
CSV, a bare object from NDJSON, XmlStreamRow from XML. Every one now
yields StreamRow<T> = { index, sheet, values } and every one is an
AsyncGenerator, so one for-await loop holds across formats. streamCsvRows
was the one synchronous generator.
streamOdsRows walked every sheet while streamXlsxRows walked one; both
now take sheet?: number | string, default the first, and ODS resolves a
name instead of falling back to everything. sheet: "all" keeps the old
walk. streamNdjsonRows and streamXmlRows take any ReadInput or a string.

… gone SpreadsheetStreamWriter.finish() was string | Promise<Uint8Array>; its own doc comment called converging the two a breaking decision. It is Promise<Uint8Array> on all four writers; CsvStreamWriter and NdjsonStreamWriter keep the string form as finishText(). toStream() leaves XlsxStreamWriter, CsvStreamWriter and OdsStreamWriter, where it buffered everything and handed over one chunk — a stream in name only, with a README warning to say so. NdjsonStreamWriter keeps it; it releases rows as written. CellInput = CellValue | Partial<Cell> replaces StreamStyledCell, OdsStyledCell, OdsIncrementalCell, OdsWriteCell and OdsWriteRow — five names for one shape. OdsStreamWriter declares the interface it already satisfied. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UU3YfLMdFvTcXyVFyXb28e
The same question was asked under different names in different bags. CSV read's header: true is hasHeaderRow, the name toHtml and toMarkdown already used; CSV write's headers: false is writeHeader: false and headers is string[] only; writeHeaders on the objects writers is writeHeader; the streaming XLSX writers' inlineStrings is stringMode, the name writeXlsx already used, defaults unchanged; is1904 on serialToDate/dateToSerial/formatValue is dateSystem, the spelling every reader and writer already used. sheetToObjects skips blank rows by default like the rest of the *Objects family and takes skipEmptyRows; it hard-coded the opposite. JsonReadOptions.transformValue gets colIndex, like every other one. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UU3YfLMdFvTcXyVFyXb28e
…r, new entry points read() assumed any ZIP was XLSX and failed inside readXlsx; a .docx or a plain archive is refused up front with UnsupportedFormatError. Eighteen plain Error/TypeError throws — argument misuse in the chart helpers, cloneChart, the pivot writer, the incremental writers — are InvalidArgumentError, so instanceof HucreError is the catch-all the docs claimed. moveSheet/removeSheet check their indexes instead of splicing undefined. hucre/cell, hucre/format and hucre/a11y are entry points; hucre/xlsx carries every cell helper (#474). SchemaValidateOptions, AuditOptions, WriteFormat, TextFormatOptions and OdsStreamReadOptions are exported. openXlsx takes ReadInput. The CLI's convert carries the whole authoring model rather than { name, rows }; validate declares --encoding and takes --header-row. CHANGELOG.md starts. Size budgets lowered to the smaller root bundle. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UU3YfLMdFvTcXyVFyXb28e

In `@MIGRATION.md`:
- Line 11: Update the “At a glance” table in MIGRATION.md to include rows
linking to every remaining major breaking-change section documented below,
including per-reader options, Color, CellError, rectangular Sheet.rows,
streaming, writers, and option names. Preserve the existing Deprecated names
removed row and use the exact section anchors and migration terminology already
defined in the document.
In `@README.md`:
- Line 2065: Update the CsvStreamWriter API table entry to document finish() as
returning Promise<Uint8Array>, matching the SpreadsheetStreamWriter contract;
leave the finishText() string description unchanged.
- Line 561: Update the README example’s hucre type import to include CellValue
alongside SpreadsheetStreamWriter so the exportAll function’s rows parameter
resolves when copied as TypeScript.
- Line 1708: Update the NDJSON response flow around writer.finish() so it does
not finalize the writer before creating the stream. Use
writeNdjsonStream(source), or keep toStream() active while the producer writes
rows and calls finish() on completion; alternatively await finish() and pass the
returned bytes directly to Response.
In `@src/_grid.ts`:
- Around line 10-14: Update padToRectangle in src/_grid.ts to reject rows.length
multiplied by the computed width when it exceeds the rectangular cell limit,
before any padding occurs; apply the corresponding limit at the call sites in
src/defter.ts:185, src/export/html-import.ts:460, and src/ods/reader.ts:968,
with no direct change needed elsewhere.
In `@src/cli/commands.ts`:
- Around line 493-495: Update the headerRow validation in the validate command
after the selected sheet is loaded so nonnegative values greater than or equal
to sheet.rows.length are rejected, while preserving -1 and valid in-range
indexes. Ensure out-of-range values raise the existing CliError instead of
allowing validateWithSchema to process an empty header.
- Around line 477-482: Update the filePath === "-" stdin branch in the validate
command to pass the requested encoding into readStdin before calling read, while
preserving the existing readFile encoding behavior for regular files.
In `@src/defter.ts`:
- Line 156: Update the ZipReader initialization in the ZIP preflight to pass
options?.maxDecompressedBytes as the decompression limit, preserving the
configured limit instead of relying on the default 2 GiB limit when extracting
[Content_Types].xml.
In `@src/export/markdown.ts`:
- Line 64: Update the isCellError branch to pass value.error through escapeCell
before returning it, preserving the existing handling for all other cell values.
In `@src/json/writer.ts`:
- Around line 18-21: Update errorReplacer in src/json/writer.ts at lines 18-21
to normalize only known cell-value leaves, avoiding isCellError checks on row or
nested container objects. In src/json/unflatten.ts at lines 106-108, recognize
generated null-prototype containers before checking for CellError leaves,
preserving ordinary objects with error properties as data.
In `@src/ods/incremental-writer.ts`:
- Line 141: Update addObject to validate every entry in columns has a key before
mapping object rows; reject configurations containing a keyless column, while
preserving the existing missing-columns validation and normal mapping for valid
column definitions.
In `@src/sheet-ops.ts`:
- Line 1352: Update replaceCells and its syncCellOverride path so replacing a
CellError also synchronizes the corresponding Cell.type, reusing the existing
value-to-type mapping used by the template path. Add a Map-backed test covering
replacement of an error with a non-error value and verify both value and type
are updated.
In `@src/xlsx.ts`:
- Around line 79-80: Export XlsReadOptions from the hucre/xlsx entry point
alongside XlsxReadOptions and XlsbReadOptions so consumers of readXls can import
its option type without a TypeScript module export error.
In `@src/xlsx/worksheet-writer.ts`:
- Around line 1040-1041: Update the isCellError branch to XML-escape value.error
before passing it to simpleCell, matching the existing escaping used by the
formula-result branch while preserving the cell type and other arguments.

Use one NDJSON output path.
NdjsonStreamWriter.finish() sets done synchronously and returns Promise<Uint8Array>. This code therefore finalizes the writer before toStream() is created. The stream only drains the buffered rows, so it does not provide live, constant-memory output. Use writeNdjsonStream(source), or return toStream() while a producer adds rows and calls finish() when it completes. Otherwise, await finish() and pass its bytes to Response.

Do not classify JSON containers from an error property alone.
isCellError treats any object with error: string as a cell error. This loses ordinary spreadsheet data. For example, {"status.error":"failed","status.code":500} cannot unflatten correctly, and a row with an error column can be replaced by its error string during JSON.stringify.

Reject columns without key in addObject.
Line 141 only rejects a missing columns array. With columns: [{ header: "name" }], addObject({ name: "Ada" }) writes null at Line 144. This silently loses object-row data. Reject any column without a key before mapping the row.
Proposed fix
- if (!this.columns) {
+ if (!this.columns || this.columns.some((column) => !column.key)) {
throw new InvalidArgumentError("addObject requires columns with key accessors")

Synchronize Cell.type when replacing an error value.
This new comparison makes a CellError match reachable in replaceCells. If the sheet has a corresponding sheet.cells entry, syncCellOverride updates only existing.value. Replacing the error with a non-error value leaves existing.type as "error", so the Cell record becomes inconsistent and can serialize with the wrong cell type. Update the type with the same value-to-type mapping used by the template path, and add a Map-backed replacement test.

Escape the error token before writing XML.
isCellError accepts any object with error: string. This branch passes that string directly to simpleCell. For example, { error: "A&B" } produces invalid worksheet XML. Escape the token as the formula-result branch already does.
