Import CoinGecko Data to Google Sheets

Last Updated On

In this guide, we’ll walk through how to pull cryptocurrency market data from the CoinGecko API directly into Google Sheets, using the API Connector add-on for Sheets. The cool thing about CoinGecko is that their API is free and open, so we won’t need any API key. They also provide some unique API endpoints like most-searched coins.

If you want to skip the details, you can jump right to the end to grab your own copy of the CoinGecko crypto tracking template. You can also check out our YouTube tutorial video here.

BEFORE YOU BEGIN

Click here to install the API Connector add-on from the Google Marketplace.

PART 1: CREATE YOUR COINGECKO API REQUEST URL

We’ll first follow the CoinGecko API documentation to access the current price of ETH (Ethereum).

  • API root: https://api.coingecko.com
  • Endpoint: /api/v3/coins/markets
  • Query String: ?vs_currency={currency}&ids={coin ID}
    Query String Example: ?vs_currency=usd&ids=ethereum

Putting it together, we get the full API Request URL:

https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=ethereum

PART 2: PULL COINGECKO API DATA INTO SHEETS

Now let’s paste that URL into API Connector and import some crypto data into Google Sheets.

  1. Open up Google Sheets and click Add-ons > API Connector > Open.
  2. In the Create tab, enter the API URL we just created.
    coingecko-img1
  3. Leave the Headers section empty. We can leave authentication set to None, too.
  4. Create a new tab and click ‘Set current’ to use that tab as your data destination.
  5. Name your request and click Run. A moment later you’ll see the latest exchange rate data for Ethereum to USD appear in your Google Sheet:
    coingecko-img2

PART 3: MORE EXAMPLE API URLS

Experiment with endpoints and query strings as described in the documentation to see other types of currency and crypto data from the API. For example, you can try the following URLs, one at a time (substitute in other coin IDs or currencies, if you like).

  • current price of bitcoin in USD
    https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd
  • all supported cryptocurrencies with price, market cap, volume, and other stats
    https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd
  • specific cryptocurrencies with price, market cap, volume, and other stats
    https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids=bitcoin,ethereum,ripple,eos
  • historical price snapshot of Bitcoin at a specified date
    https://api.coingecko.com/api/v3/coins/bitcoin/history?date=30-12-2018
  • list of all supported coins with ids, names, and symbols
    https://api.coingecko.com/api/v3/coins/list
  • list all exchanges and related info (year established, country, trade volume, etc)
    https://api.coingecko.com/api/v3/exchanges
  • get exchange rates for BTC in every currency
    https://api.coingecko.com/api/v3/exchange_rates
    coingecko-img7
    By default the /exchange-rates request URL will return all exchange rates in a single row. To split the data into a table, you can add in a JMESPath (paid feature) query of rates.* as shown in the screenshot above.
  • most-searched coins on CoinGecko in past 24 hours
    https://api.coingecko.com/api/v3/search/trending

PART 4: HANDLE PAGINATION

  1. For several endpoints, CoinGecko limits the number of records returned in each response. By default, only 100 records will be returned unless you use the ‘page’ and ‘per_page’ parameters as shown in their documentation.
    coingecko-img5

    To get 250 records, you’d use the ‘per_page’ parameter and to return more than 250 you’d then make a second request using the ‘page’ parameter. For example:
    page 1: https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&per_page=250&page=1
    page 2: https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&per_page=250&page=2

  2. With API Connector you can either run these URLs manually or loop through them automatically with page parameter pagination handling (paid feature), like this:
    • API URL: enter your request URL as usual, making sure to include per_page=250
    • Pagination type: page parameter
    • Page parameter: page
    • Number of pages: enter the number of pages you’d like to fetch

APPENDIX: COINGECKO TEMPLATE

In this template, everything is configured for you to simply type in whatever coins you’re interested in and get a dashboard like below:

  1. Hey so i did this but it seems like it doesn’t keep up with the price fluctuations and it just stays at the original price when i set up the API, do you know the reason why this is happening?

    Reply

    • Good question. For markets, by default CoinGecko limits the amount of records they return at once. To get more you need to add &per_page=250&page=1, &per_page=250&page=2, &per_page=250&page=3, and so on to the end of your URL. I’ve just updated the article to reflect this.

    • Hey there, this is due to the way they’ve structured their response data. If you check it in an API tool that returns the raw JSON (e.g. Swagger), you’ll notice that the response from CoinGecko uses named objects where normally you would see arrays. This prevents API Connector from recognizing where to split the data into columns vs. rows when converting the JSON response into Sheets format.
      In any case, to answer your question, you can use JMESPath, which is a very useful query language that allows you to filter and restructure the response data. The query rates.* removes the object names so that the response can be parsed correctly. I added a screenshot of this to the article.
      Note that JMESPath filtering is a paid feature, if you’re trying to do this for free, one other option is to create a second sheet containing a Sheets function like =transpose(Exchange_rates!1:2) to convert the response from one long row to one long column. I don’t think it’s a great solution but it’s still a bit better than the default response.

  5. Hi Ana

    I came up with 3 solutions for this problem.

    Solution 1 & 2 require you to enter the formula in the first Row of 4 cells. Then drag the formula down in this case for 61 Rows since there are 61 rates returned by the API (a horizontal row of 4×61=244 cells)

    Solution 3 returns the whole table,
    after you enter the formula in the top left cell where you want the table

    Solution 1:

    =INDEX($7:$7,(ROW()-11)*4+COLUMN())

    Solution 2:

    =OFFSET(A$7,0,(ROW()-11)*4)

    Solution 3:

    Note this assumes the API data is returned on Row A7:7 – just change that to suit your Row.

    =arrayformula( query( query( iferror( if( {1,1,0}, floor( mod(row(A:A)-{1,1},{9^9, 4}), {4,1} ), transpose( split( regexreplace( query( transpose( query( transpose(A7:7 & char(9)), “”, 9^9 ) ), “”, 9^9 ), “\s+$”, “” ), char(9) & ” “, ) ) ) ), “select max(Col3) where Col3 ” group by Col1 pivot Col2″, 0 ), “offset 1”, 0 ) )

    Solution 3 is care of the experts at Docs Editors Help.

  6. In the message above showing Solution 3 I was using the following
    URL Path = https://api.coingecko.com/api/v3/exchange_rates

    To use the Solution 3 above you need two Google Sheets
    1 – Results Sheet (This is where the table will display)
    2 – Data Sheet (This is where the API writes its ouput)

    Also where you see the function – transpose(A7:7 – this shows my data was being read from row7 – BUT –

    You should point to the sheet holding your Data with – transpose(‘Data’!A2:2 & char(9)

    Results Sheet
    =============
    Col A Col B Col C Col D
    Row(1) rates » btc » name rates » btc » unit rates » btc » value rates » btc » type
    Row(2)

    Data Sheet
    ==========
    This is where the API Connctor will put the data.
    1 – URL Path = https://api.coingecko.com/api/v3/exchange_rates
    2 – Output Option = Overwrite
    This means the data will always be written on to Row(2) starting with Cell A2

  7. Is it possible to use the template but expand it to go beyond just 30 inputs? (I have around 100 coins I want to track). Can anyone help with what changes I would need to make?

    Thanks

    Reply

    • Should be possible, just do the following:
      1) in the Inputs tab, add in as many rows as you want
      2) in the Summary tab, change the Query formula in cell B8 to read from your new input rows

      • 429 errors mean you’re hitting their rate limits. The rate limit for the CoinGecko API is 10 calls each second per IP address. Unfortunately it’s easy to run into these limits, since all Sheets calls are routed through Google’s IP address pool, meaning other people are using the same resources. It should work if you wait a minute and try again.

      • Good question, I checked and I think it’s because this request sheet is set up to look for the ID rather than the symbol. In this case, the ID is “republic-protocol” while the symbol is “ren”. In many cases the ID and symbol are the same, so that’s why this problem isn’t always evident. I’ll try to make that more clear.
