  • export_xlsx

    Return the workbook as base64-encoded .xlsx bytes. Last resort. The bytes land in your context and cost roughly 1.4 KB of text per KB of file. Prefer `save_workbook`, which writes a real file and hands the host a link to it — the host can give the human the workbook without any of it passing through you.

  • open_workbook

    Start the workbook you will work in. Call with no arguments for a fresh, empty one; pass `path` to load an existing .xlsx from disk and work on the human's real file. This replaces whatever workbook the session currently holds, discarding unsaved changes — so call it once at the start, not between steps. You do NOT have to call it at all: an empty workbook appears automatically the moment any other tool touches the session. Prefer `path` over `xlsx_base64`. `xlsx_base64` exists for hosts with no shared filesystem and costs enormous context for a file of any size.

  • save_workbook

    Write the workbook to a real .xlsx file the human can open in Excel. This is how you hand your work back — do it when the task is done. Defaults to the path it was opened from, or last saved to; pass `path` to write somewhere else. Values, formulas and the block structure are all saved. IMPORTANT — if the human is going to work on this in Excel, pass `resolve_block_refs: true`. Formulas that read blocks are written as BLOCKREF/BLOCKREFS, which only LogiSheets understands: Excel shows the saved numbers but turns those cells into #NAME? the moment it recalculates. Resolving rewrites them as or…
