paged.sheet — live spreadsheets in print

Excel workbooks, set in the layout

A spreadsheet engine in the page: real Excel workbooks with live formulas, tables and charts that paginate like print, and save back as XLSX.

A real calculation engine

263 functions, checked against Excel

paged.sheet is a Rust spreadsheet engine compiled to WebAssembly. All 263 registered functions are implemented, LET and LAMBDA with its helpers among them; dynamic arrays spill and nest; Excel tables answer structured references; recalculation is incremental, volatile cells carry their dependents, and iterative calculation runs when the workbook asks for it.

The proof is Excel itself. Recalculating real workbooks reproduces the value Excel saved in the file for 93.6% of comparable formula cells — shared formulas, defined names, whole-column references, legacy array formulas and all.

Formulas, spill and the roster: a lowered range prints results — a SUM, an uppercase call, a SEQUENCE spilling from one anchor — above the function library by family, counted when the Annual was built (224 then; 263 now).

A range on the page

Native tables that follow the workbook — and paginate

Place a range and it becomes one text frame holding a native table: the workbook’s fills, borders, fonts and conditional formatting, merged cells, numbers aligned right, column widths measured with the document’s own font metrics, and data bars drawn under the table.

Edit the workbook and every placed table refreshes in place — only changed cells re-poured, in one document write and one undo step. One command threads a long range over linked frames, repeats the header rows in every frame, and re-paginates when a frame is resized.

The Ledger opener: a spreadsheet in a page document leads two lives — the live grid you type into, and what the plugin lowers to native content that persists.

The grid in the frame: Click, drag and shift selection, arrows, Tab and F2, a cell editor with function completion, copy and paste with references re-addressed, the fill handle with series.
The Workbook panel: Sheets, ranges, sort, find and replace, charts, cell styles, number formats, borders, merge, freeze, defined names, rows and columns.
Undo that makes sense: Every committed cell edit is one step; so is each sort, paste, fill and format change.
Five display locales: Number formats render in five locales, taken from the workbook on load.

Charts

Ten kinds, drawn as paths — never a picture

Charts are read from the workbook or authored over a range, then placed as vector paths and labelled text frames in one document write — and replaced in one write when their data changes. Their colours are document swatches; the host’s Swatches panel edits the workbook’s chart colours.

The Paged Annual — chart-wall — The chart wall: one workbook, ten charts — column, bar, stacked column, stacked bar, line, area, pie, donut, scatter and radar. Every bar, wedge and spoke is a native path; every axis number is a text frame.

Live — paged.sheet as its own application

The spreadsheet, in this tab

Solo mode boots the real editor as paged.sheet. Open an .xlsx, CSV or TSV file or start a blank workbook; the calculation runs in your browser and your file stays on your machine.

How it lives in a document

The workbook travels as XLSX; the page is native

The workbook’s own bytes are stored in the .paged container and re-saved after every committed edit, so a reload restores the edited workbook. What the page shows — tables, data bars, charts — is lowered to native frames, tables and paths, so InDesign opens the IDML and sees real tables, not images.

Export writes an .xlsx in which every part the session did not touch keeps its original bytes — pivot caches, macros and parts the engine never interprets included.

A publishing instrument with a real engine underneath.
