KEY FEATURES - Built-in AI formula assistant: ask in plain language and get formulas auto-filled into your selected cells - Zero-install AI engine: the language model ships inside the app, so AI features work fully offline and keep your data private - Import & export Excel (.xlsx) and CSV files - Insert images directly into your spreadsheet - Rich editing tools: bold/italic/underline, alignment, number formats, cell merging, row/column operations, and more - Available in Traditional Chinese, Simplified Chinese, and English WHO IT'S FOR Whether you're managing a budget, analyzing data, or building quick reports, Excelkiln is your on-the-go spreadsheet companion. All AI processing happens entirely on your device — your spreadsheets are never uploaded to any external server. DEVICE RECOMMENDATION For the best AI performance, we recommend iPhone 14 Pro or newer (or any device with 6GB+ RAM). Older devices can run the app but AI generation may be slower.
