Stock Portfolio Spreadsheet

Managing and tracking your investment portfolio is a crucial aspect of successful financial planning. While there are many sophisticated tools available for this purpose, creating a simple and personalized stock portfolio spreadsheet tracker in Google Sheets can offer a high level of customization and control. In this article, we will guide you through the process of building a portfolio tracker using APIs (Application Programming Interfaces) in Google Sheets.

It’s worth checking our ready-to-use EODHD Add-in for Google Sheets, which could help you to get reliable information directly into your spreadsheet. If you are looking for an Excel portfolio tracker spreadsheet please check the following article.

Setting Up Financial Spreadsheet

Google Sheets Start by opening a new Google Sheets spreadsheet and organizing it with the necessary columns. Common columns include “Ticker,” “Company Name,” “Quantity,” “Purchase Price,” “Current Price,” and “Market Value.” You can add additional columns based on your preferences, such as dividend yield, sector, or any other relevant information.

API Requests for Dynamic Spreadsheets

Now you have bones of the future portfolio tracker and you need to populate it with data. To create a dynamically updatable spreadsheet we will use Google Sheets’ functions which call data using external URL requests. The most commonly used function is ‘=IMPORTDATA()’.

IMPORTDATA for Financial data extraction

EODHD provides all the necessary data you need to track your portfolio efficiently. In the article, we will be using a couple of them to give you the basics of working with EODHD APIs:

We recommend you register a free account to get free access to some of our APIs:

Working with API requests

To get the needed data efficiently you need to visit a documentation page of the API. There you can understand how requests and received data are structured.

For live API you can open the link and browse the page to find necessary information. It’s important to understand the functionality and potential output of the API to implement it effectively.

How to use Financial APIs

To insert the live data into the cell we will use the following function:


Note that in the function we use cell values to get ticker (B11), market ($C$8), and API token information ($C$5). The URL itself contains a filter parameter “&filter=close” which will limit the output for the Live API to close price only. “&fmt=json” URL parameter sets output in JSON, for live data we can also choose CSV, however, in this case, we have cleaner data with JSON output.

Importdata for live stock prices

You can find your API token on your Settings page after the registration. You can also use a “demo” token to get data for AAPL, MSFT, AMZN, and TSLA tickers. The spreadsheet used a demo token you can change it on yours.

Plot Stock Performance Using Historical Data

Having a price chart always helps to get a better understanding of sporting trends, to get Historical data for the line chart we will use the End-of-Day API. You can find an example on a Price Chart bookmark of the template spreadsheet.

IMPORTDATA for historical stock prices, how to plot data

Here price chart is generated on selected stock from your portfolio from the time it was bought.

To insert historical data for the plot into table we will use the following function:


Here we also use cell values for ticker($B$3), market(Portfolio!$C$8&), and API token(Portfolio!$C$5). However, for the price range, we need to get a date from the cell in the proper format for this we use the ‘TEXT($C$3,”YYYY-MM-DD”)’ function.

For the stock selected, we used ‘Dropdown‘ menu from the range, and for the automatically updated date used ‘VLOOKUP‘ function.

Financail Ratios Data

One of the core principles of fundamental investing is the analysis of corporate financial ratios. In the spreadsheet, we are using Fundamental API to get core analytical data for the portfolio’s stocks.

To insert fundamental data into the spreadsheet we will use the following function:


As previously we cell values for ticker($B$3), market(Portfolio!$C$8&), and API token(Portfolio!$C$5). In this case, we also need to use the ‘TRANSPOSE‘ Google Sheets function to get the data into the column instead of a line.

TRANSPOSE and IMPORTDATA with the Fundamental Financial Data

For the ratios on the main ‘Portfolio’ page, we use Google’s ‘SUM’ function and algebraic operations supported by the spreadsheet. You can check it by clicking on the cells.

Add New Tickers

To add new tickers you need to poot the ticker code into the left cell of the portfolio table, add the purchase date and the stock price of the transaction.

After you need to simply drag previous cells down and all ratios and current data will be updated in an instance. You can see how it’s done below.
