Office & Mobile Suites
Arte Sheets vs Polaris Office Sheet
When Arte Sheets fits best
- Zero banner ads, zero interstitial video ads on mobile, and no device-count cap when opening the browser editor.
- Free .xlsx, .csv, .tsv, and .ods import/export without registration; local workbooks remain privately in browser IndexedDB.
- Includes 2,950+ interactive spreadsheet guides and optional Pro AI (2,000 monthly credits) with voice and file-excerpt support.
When Polaris Office Sheet fits best
- All-in-one native mobile and desktop viewer/editor for Word (.docx), PowerPoint (.pptx), HWP, PDF, and Excel (.xlsx) files.
- Preserves embedded Excel charts inside .xlsx files and offers native iOS/Android file-association handlers.
- Offers lower-cost ad-removal tiers (Polaris Smart/Pro ~$39.99–$59.99/yr) when you need multi-format office editing.
Ad-Free Focus and Unlimited Browser Access vs Freemium Device Caps
Freemium multi-document suites like Polaris Office monetize casual spreadsheet users through ad placements, monthly cloud-traffic limits, and connected-device caps unless you upgrade. On a phone or tablet screen, ad banners shrink the visible grid right when you are trying to inspect columns.
Arte Sheets is dedicated exclusively to spreadsheets and spreadsheet mastery. Every pixel of the editor goes to your cells, formula bar, and charts—with zero ads on any tier and no artificial limit on how many computers or tablets you open the browser app from.

Spreadsheet Engine, Dynamic Arrays, and Export Fidelity
Arte Sheets runs its calculation and import/export pipelines inside browser Web Workers so CSV, TSV, and .xlsx files load smoothly without freezing the page. Its 184-function catalog includes modern Excel dynamic arrays (XLOOKUP, FILTER, UNIQUE, SORT, VSTACK, TEXTSPLIT) plus formula-auditing arrows.
Polaris Sheet supports 300+ traditional spreadsheet functions and keeps embedded .xlsx charts intact when resaving Office files, making it handy if you routinely annotate mixed .docx, .pptx, and chart-heavy .xlsx bundles in one mobile app.
