Import spreadsheet data
Open Excel, CSV, TSV, or JSON. XLS Studio parses every sheet, restores formulas where possible, and autosaves locally in IndexedDB.
Share this workbook
Creates a server-free URL with the entire workbook encoded into the hash. For very large workbooks, prefer the Export library backup JSON file.
Load Vibe
Paste an xls-vibe JSON payload, a Luckysheet/SheetJS workbook JSON, CSV, TSV, or an array of objects. Auto-detected and loaded into the spreadsheet with the right theme.
XLS Studio — Help & API

Spreadsheet engine

Powered by Luckysheet — Excel-compatible formulas (SUM, VLOOKUP, INDEX/MATCH, IF, IFERROR, date math, 400+ functions), merged cells, freeze panes, conditional formatting, and right-click context menus.

Multi-sheet workbooks

Use the bottom tab bar (in Luckysheet) to add, rename, reorder, and switch sheets. Every workbook can hold many sheets, just like Excel.

Vibe links

The Vibe menu emits a #vibe= URL carrying the whole workbook. Paired with the xls-vibe skill, an LLM can generate sheets from any input and return a clickable link.

Smart paste

Load Vibe accepts xls-vibe JSON, raw CSV/TSV, JSON arrays of arrays, or arrays of objects. Auto-detected.

JS API

window.XLSStudio.load(data, "Title") · .getWorkbook() · .exportXLSX() · postMessage({type:"xls-load", payload, title}).

Shortcuts

⌘S save · ⌘N new · ⌘O import · ⇧⌘V Load Vibe · ⌘. focus mode. Standard Excel shortcuts (⌘C/⌘V/⌘Z/⌘Y, arrow nav, F2) work inside the grid.
