Conflicts:
- crates/model/src/lib.rs, crates/xlsx/src/read.rs, crates/xlsx/src/write.rs: use lists unioned (ShowObjects and the phonetic types)
- docs/file-format-parity.md: main's header and rows kept (#1692 collapsed the three duplicate .xlsx rows; they stay), phonetic-runs text added to each; Last updated 2026-10-20
crates/xlsx/src/styles.rs: family/charset block ported into the dxf.is_none() branch of font_xml (PR #1225 made it take Option<&DxfStated>)
docs/file-format-parity.md: header Change line keeps both sides' clauses
Conflicts:
- docs/file-format-parity.md: header and the three .xlsx rows keep main's text plus the show-objects entry; both log rows kept
- docs/ui-parity.md: header keeps main's text plus Ctrl+6; both log rows kept
Conflicts:
- docs/file-format-parity.md: kept main's three .xlsx rows (the PR's docs hunk replaced them with one) and added the theme-font wording to each; header keeps main's change list plus this PR's phrase (updated 2026-10-20)
crates/engine/src/tests.rs: kept both sides' new tests (journal tests from #1230, HTML export tests from the PR).
docs/file-format-parity.md: header Last updated 2026-10-21 with both change clauses; both revision-history rows, newest first.
si_body returned as soon as no valid run was written, so a shared string with a
<phoneticPr> and no <rPh> — a shape §18.4.8 allows — lost its properties on
save even though the reader keeps them. The runs and the properties are now
written independently: valid runs as before, then the valid <phoneticPr> when
the workbook has one; with neither, the <si> is exactly the plain t_el output.
property_only_shared_string_survives_open_and_save covers read, save and
reopen, and the si_body damaged-data test now expects the property-only output.
The write-time checks the reader also runs (sb/eb clamped into the UTF-16
length, empty readings skipped, type/alignment filtered through the shared
PHONETIC_KINDS/PHONETIC_ALIGNMENTS) were already in the head; the tests above
pin them, so no further change there.
Docs: the .xlsx row and the revision history now state that the shared string
table holds each text once, so duplicate <si> items with the same text but
different readings keep only the first reading (reported as a warning on open),
and that a <phoneticPr> without runs is kept. Both parity docs' "Last updated"
headers match their 2026-10-20 revision rows; the earlier rows keep their dates.
The reader took only <x:Visible/> from a note's VML shape and vml_xml
wrote every note with a fixed anchor (two columns right of the cell,
four rows tall) and a 108 x 59.25 pt style, so a plain open and save
moved and resized every note box Excel had stored.
Comment gets an optional NoteBox: the <x:Anchor> corners relative to the
note's cell (so the box follows the note when rows or columns move) and
the shape's width and height. The writer puts it back, clamped to the
sheet; notes made here, and boxes equal to the default, keep the
default box.
Save as Web Page wrote only the cell table, so pictures and charts on a sheet
were dropped. A sheet that has either now keeps its own geometry and draws them:
- The table gets the sheet's column widths and row heights (`table-layout:fixed`,
a `<colgroup>`, a height per row); hidden columns and rows take no room and
merged-cell spans count only visible lines.
- A picture is an `<img>` with a `data:` URI, a chart is inline SVG built from
the chart crate's drawing primitives (titles, axes, legends and data labels
included), each absolutely positioned at its anchor cell plus offset.
- Sheets without pictures or charts write byte-identical HTML.
Adds contributors/people.toml entry for bilalmughal.
xl/sharedStrings.xml can carry phonetic runs (<rPh sb="0" eb="2"><t>ふりがな</t></rPh>)
and a <phoneticPr> beside a string item. GridCraft read only the text and wrote every
string back as <si><t>…</t></si>, so a plain open + save deleted a Japanese workbook's
furigana.
Both are now read — offsets validated against the base text, runs with bad or missing
offsets, sb >= eb or no reading dropped with a warning, and never used to index — and
kept on the workbook as Workbook::phonetics, one entry per string text. The writer
emits them next to the <si> of the same text. The saved table holds each text once, so
two identical texts cannot keep two different readings: the reader keeps the first and
warns. Strings without phonetic data are written byte for byte as before.
Behaviour reference: ISO/IEC 29500-1 §18.4.6 rPh and §18.4.7 phoneticPr (Microsoft
Learn PhoneticRun/PhoneticProperties). Tests: crates/xlsx/src/tests/phonetic_tests.rs
(round trip, plain string, hostile offsets, shared text, unused data, comments and
inline strings). Docs: file-format-parity.md, localization-parity.md.
A theme's <a:fontScheme> carries latin, ea (East Asian) and cs (complex
script) typefaces for each of the major and minor fonts. The model held
only the latin ones and the writer emitted <a:ea typeface=""/> and
<a:cs typeface=""/> unconditionally, so a Japanese workbook's theme fonts
(e.g. 游ゴシック, ＭＳ Ｐゴシック) were silently deleted on open + save.
Theme gains major_font_ea, minor_font_ea, major_font_cs and
minor_font_cs (#[serde(default)], so older GridCraft JSON still loads;
empty means the file did not set one). The XLSX reader and writer
round-trip them escaped, and a theme without them writes exactly the
empty attributes it wrote before.
Rendering and font resolution are unchanged: the UI does not consume ea
yet, and wiring it in is a follow-up.
rowGrandTotals is the Grand Total row under the report and colGrandTotals the
Grand Total column at its right. Both were mapped the other way round; a
GridCraft round trip hid it, but an Excel file with only one grand total opened
with the other one.
file.open takes {csvAsText: true}: a CSV, TSV or TXT file opens with every field as the text
it holds, with no number, date or boolean conversion, so identifiers such as GTINs, SKUs and
ZIP codes keep their digits and leading zeros and save back unchanged. The default is
unchanged. The CsvOptions.parse_values switch already existed in the reader.

Checked black-box in Excel for Windows (Microsoft 365) with synthetic
workbooks: a bare name in <c:f> draws the whole chart blank, without a
repair prompt, for workbook- and sheet-scoped names alike, while
`[0]!Name` and `Sheet1!Name` plot.
- Write: a sheet-scoped name is written `Sheet!Name` (quoted when
needed) instead of bare; an already qualified name keeps its sheet;
an undefined name gets `[0]!`. A reference to an unknown sheet is
kept as written. A qualified series name is written as a strRef.
- Resolve: a series name `Sheet1!Name` is looked up on that sheet, as
the evaluator does, instead of being shown as literal text.

Excel writes a workbook-scoped defined name in a chart reference as
`[0]!Name`. The reader kept that text, the lexer took `[0]` for a
structured reference, and the series evaluated to #NAME?: a chart over
dynamic (OFFSET) names opened blank with one #NAME? category.
- Read: `[0]!Name` becomes `Name` in c:f (cat, val, xVal, yVal,
bubbleSize, tx), chartex cx:f and _xlchart names. External books
([1]Sheet1!...), quoted sheet names and strings are untouched.
- Write: a bare workbook-scoped name is written back as `[0]!Name`; a
sheet-scoped name stays bare. A series name that is a defined name is
written as a strRef instead of literal text.
- Resolve: a series name that is a defined name is evaluated.
