Cryptocurrency Investors Build Live Portfolio Trackers Using Google Sheets and CoinGecko API

With the increasing volatility and round-the-clock trading nature of cryptocurrency markets, investors are seeking efficient and customizable tools to monitor their portfolios. A new solution has emerged that allows users to build a live crypto portfolio tracker using Google Sheets and the API Connector add-on by Mixed Analytics, leveraging CoinGecko’s API for real-time data [1].

The method offers a step-by-step process for non-technical users to set up a personalized portfolio tracker without needing to write code. After installing the API Connector extension from the Google Workspace Marketplace, users can link it to CoinGecko’s API using either a free or paid API key. The free version provides sufficient functionality for most basic tracking needs, while the paid tier offers advanced features such as scheduling and increased API request limits [1].

Once the API key is obtained, users can configure API requests to pull live market data into their Google Sheets. The guide recommends selecting the “/coins/markets” endpoint for comprehensive market data. By customizing parameters such as currency and pagination settings, users can fine-tune the data to match their investment focus [1].

A key feature of the setup is the ability to handle pagination. CoinGecko’s API limits the number of records returned per request, so users can automate the retrieval of multiple pages using API Connector’s built-in pagination tools. This ensures that large portfolios or extensive market data sets can be accurately represented within the spreadsheet [1].

After importing the data, the guide walks users through configuring the spreadsheet to act as a portfolio tracker. Additional columns can be added for tracking current holdings, total investments, and return on investment (ROI). Using array formulas, these metrics can be dynamically calculated based on the imported price data. To prevent these custom fields from being overwritten during future data updates, the guide recommends adjusting the output settings in API Connector [1].

For convenience, the template is also available for free download, allowing users to skip the setup process and directly import their CoinGecko API key and list of cryptocurrencies to begin tracking immediately [1].

The approach aligns with broader trends in the crypto space, where self-sovereign tools and DIY financial management are gaining traction. By enabling users to build their own trackers, the method supports greater transparency and control over investment decisions, without relying on third-party platforms.
