Cryptfolio Scripts

A collection of Google Apps Script custom functions for tracking crypto portfolios in Google Sheets.

The price data is pulled using CoinGecko's API, and the token balances are obtained by making queries to various RPC servers like PublicNode.

If this project helped you, consider buying me a coffee via 3Cities or GitHub Sponsors.

How to Use

1. Obtain a CoinGecko Demo API by following the instructions
   here.
2. Open the Cryptfolio template in Google Sheets.
3. Click on "File", and then "Make a copy". This will create a copy of the template in Google Sheets.
4. From the toolbar, click on "Extensions", and then on "Apps Script". You should be able to see the code now.
5. Add the chains and tokens you want to track in the chainIDs and tokenData variables.
6. Query the price data by running the GET_ALL_PRICES function.
7. Use the GET_ERC20_BALANCE and GET_NATIVE_BALANCE functions to query your holdings in real-time.
8. Calculate the USD value of your holdings by reading the local price data with INDEX and MATCH.

[!NOTE]

The GET_ALL_PRICES can only be run from within Apps Script. See the Custom Functions section below.

Template

The template shows how to query balances for ARB, ETH, MKR, and OP, and how to calculate the values of the holdings:

Rationale

I built this because I was frustrated with the existing solutions, which are either too complex, too expensive, or too unstable.

Cryptfolio is:

• Free to use
• Minimalist
• DYI and easy to customize
• Functional; it just works

Customization

This project is meant to be forked and customized to your needs. Here are two common use cases:

Chains

To track a new chain:

• Add it in the Chains sheet in the spreadsheet.
• Edit chainIds in cryptfolio.gs.

Tokens

To track a new token:

• List it in the Prices sheet in the spreadsheet. Ensure that the CRYPTO_IDS range got updated, too.
• Edit the tokenData object in cryptfolio.gs.

Custom Functions

Here's a table with the custom functions enabled by this project.

The Read functions can be called from either Google Sheets or Apps Script, but the Write functions can only be run from within the Apps Script environment. This is because a custom function cannot affect cells other than those it returns a value to.
