# LinkyFlow > LinkyFlow is a free Microsoft Excel add-in (Microsoft AppSource) that turns a classic spreadsheet into a dynamic, two-way workspace. It streams real-time data from crypto exchanges and e-commerce platforms straight into Excel cells, and lets the sheet perform actions back on those platforms: place crypto orders, update products, prices and inventory, and publish changes — without writing code. Key facts: - Product type: Microsoft Excel add-in (taskpane + custom functions, `=LFS.*` namespace), distributed on Microsoft AppSource (app id WA200006362). Works on Excel for Windows, macOS, iPad and Excel for the web. - Reads (live data in cells): portfolio balances, transactions, order books, live prices, OHLCV, products, variants, orders, customers, inventory, payments, payouts. - Actions (from the sheet): place/close crypto orders (`=LFS.BUY`, `=LFS.SELL`), manage futures positions and leverage, edit e-commerce products/prices/stock and publish the changes back to the platform. - Supported platforms: 9 crypto exchanges (Binance, Coinbase, OKX, Bybit, HTX, Bitget, Gate.io, MEXC, Upbit), Shopify, WooCommerce, eBay, Stripe. Roadmap: Wix, PayPal, BigCommerce. - No-code: a visual query builder (provider → query → filters → columns → Load) creates live Excel tables; one-click or scheduled refresh keeps them up to date. - Security: credentials are read-only by default; write actions require permissions the user explicitly enables on their platform. Secrets are encrypted server-side. - Pricing: free to start (market data); paid plans unlock more. ## Main pages - [Home](https://linkyflow.com/): what LinkyFlow does — live data & actions in Excel - [Documentation](https://linkyflow.com/docs): install the add-in, connect platforms, load queries, run actions - [Install the add-in](https://appsource.microsoft.com/en-us/product/office/WA200006362): Microsoft AppSource listing - [Web app](https://app.linkyflow.com): build and preview queries in the browser before running them in Excel - [Pricing](https://linkyflow.com/pricing) ## Integrations - [Crypto exchanges](https://linkyflow.com/products/linkyflow): portfolio, market data and trading in Excel - [Shopify](https://linkyflow.com/products/shopflow): products, orders, inventory — editable from the sheet - [WooCommerce](https://linkyflow.com/products/woocommerce): live store data, product updates from the sheet - [eBay](https://linkyflow.com/products/ebay): listings, orders, inventory updates - [Stripe](https://linkyflow.com/products/stripe): payments, payouts, balance reporting ## Resources - [Blog](https://linkyflow.com/blog): Excel workflows, e-commerce and crypto reporting guides
