This official add-on follows the principle of least privilege — it only accesses the sheet you currently have open. It does not request access to Google Drive or other spreadsheets.

​
Quick Start

1

Install

Visit CoinGecko for Sheets on Google Workspace Marketplace and click Install.
2

Authorize

Check Select all to grant the required permissions.
The add-on needs these permissions to communicate with the CoinGecko API and write data to your sheet. CoinGecko does NOT have access to your email or personal data.
3

Set API key

Go to Extensions > CoinGecko > Settings & API Key.
Enter your CoinGecko API key, select your plan (Demo or Pro), and click Save Settings.

​
Using =COINGECKO()

A single “Smart Routing” function that auto-detects whether you’re querying a ticker, coin ID, onchain token, or NFT.

​
Latest Price

SyntaxDescriptionExample
=COINGECKO("SYMBOL")Price by ticker symbol.

If multiple coins share the symbol, the largest by market cap is returned.

Falls back to GeckoTerminal if not found on CoinGecko.		=COINGECKO("BTC")
=COINGECKO("name:NAME")Price by coin name.

Prioritizes CoinGecko-listed tokens.		=COINGECKO("name:Ethereum")
=COINGECKO("id:COIN_ID")Price by coin ID.

Most reliable — avoids ticker conflicts.		=COINGECKO("id:solana")
=COINGECKO("NETWORK:ADDRESS")Onchain DEX price by network ID and token address.=COINGECKO("base:0x...")
=COINGECKO("nft:NFT_ID")NFT floor price by NFT ID.=COINGECKO("nft:pudgy-penguins")
Use the Coin ID (e.g. id:bitcoin-cash instead of BCH) for the most reliable results — symbols can be shared by multiple tokens.

​
Historical Price

SyntaxDescriptionExample
=COINGECKO("id:COIN_ID", "YYYY-MM-DD")Historical price at a specific date (daily 00:00 UTC).

View coin IDs.		=COINGECKO("id:bitcoin", "2025-12-31")

​
Top Market Cap Rankings

Get up to 1,000 tokens with a single formula:
SyntaxDescriptionExample
=COINGECKO("top:N")Top N coins by market cap.=COINGECKO("top:100")
=COINGECKO("top:N:CATEGORY_ID")Top N coins by market cap in a category.=COINGECKO("top:10:meme-token")

​
Other Features

​
Bulk Refresh

Google Sheets caches formulas for 1–2 hours. To force-update all =COINGECKO formulas:
Open the CoinGecko Sidebar and click Refresh All Data.

​
Error Debugging

Go to Extensions > CoinGecko > View Error Logs:
Opens a log sheet with exact API error responses (e.g. 429: Rate Limit Exceeded, 403: Invalid API Key).

​

  • View and manage spreadsheets — to populate cells with data and create error log sheets.
  • Connect to an external service — to fetch prices from the CoinGecko API.
