Simple Office

Simple Office is a lightweight add-on for basic Word, Excel, PowerPoint and PDF file work in chats, without requiring Sandbox. Install office from the add-on library. Its internal ID, tool names, settings and resource references remain office; the visible name is Simple Office. Sandbox workflows remain independent. There is no automatic fallback, routing or provider preference change.

Create documents with Markdown

create-docx and create-pdf require string fields path and markdown. Optional title is string metadata only; it does not add a visible heading.

{"path":"/reports/summary.docx","markdown":"# Summary\n\nA **bold** paragraph.\n\n- First\n- Second","title":"Report"}

Use a .pdf path with create-pdf. Both formats support headings, paragraphs, bullet and numbered lists, bold/italic emphasis, and simple rectangular tables. Inline and fenced code are literal text, never executed. Links show visible labels without fetching their targets. Raw HTML, images and unsupported constructs are rejected with an error. No network fetching, file inclusion, macros, shell commands or external converters are used.

Limits are 2000 document blocks, 100 items per list, 20 table columns and 500 body rows per table. The full JSON argument budget is 1 MiB; parsing is bounded internally. PDF retains its built-in-font Latin-1 restrictions; unsupported characters are refused before saving. No fonts or Unicode support are added by this change.

Create a single-sheet workbook with CSV

create-xlsx requires string fields path and csv; optional string sheet defaults to Sheet1, and optional string title is workbook metadata.

{"path":"/reports/status.xlsx","csv":"Worker,Status\n00123,Healthy\n","sheet":"Status"}

CSV uses commas and standard quoting, including escaped quotes and multiline quoted cells, with LF or CRLF line endings. There is no delimiter guessing. Exactly one sheet is created. The first row is ordinary data, with no implicit header styling. Every nonempty field is stored as a string: leading zeros and values beginning with =, +, - or @ are preserved, not inferred as numbers or formulas. Empty cells stay blank at their original coordinates. Use edit-xlsx afterwards for explicit numeric cells, formulas or additional sheets; its existing behavior has not changed.

Malformed quoting, ragged rows, only-empty content and invalid sheet names are refused. Limits are 5000 rows, 200 columns and 100000 grid cells, including empty fields, within the full 1 MiB JSON argument budget.

Compatibility change

The three creation tools no longer accept the old blocks (DOCX/PDF) or sheets (XLSX) structures. Update callers to markdown or csv respectively. All advertised arguments of these three tools are strings; there is no alternate structured-array creation contract. Read/edit tools and create-pptx are unchanged. Multiple-sheet creation is not supported by create-xlsx.

All paths are inside the caller’s authorized workspace, not arbitrary host paths or content URLs. Chat folder and read-only access rules still apply. Failed parsing or rendering saves no new file. Existing files are never overwritten by creation: a conflict saves the new result to a sibling path and reports it. Cancellation, authorization, extension checks and atomic workspace storage remain in force. These simplified catalog schemas are not evidence of live model tool selection or of general native grammar-parser correctness.
