Slice array in Google Sheets

Many functions in Google Sheets return an array as the result. However, I find that there is a lack of built-in support functions in Google Sheets when working with an array. For example, the GOOGLEFINANCE function can return the historical prices of a stock as a table of two columns and the first-row being headers Date and Close. How can I ignore the headers or remove the headers from the results?

Slice array in Google Sheets

Make any JavaScript method available in Google Sheets

In JavaScript, there is the SLICE method that can return a part of an array. If I have an array const pricesWithHeader = ['Close', 10.5, 10.3, 10.1, 10.0];, to get only the last 4 elements [10.5, 10.3, 10.1, 10.0], I can apply the SLICE method like const pricesWithoutHeader = pricesWithHeader.slice(1);. How to slice an array in Google Sheets?

Google Sheets has scripting capability with Apps Script based on JavaScript. So to slice an array in Google Sheets, I need to create a SLICE method in Apps Script that wraps the original SLICE method of JavaScript. By doing so, the SLICE function is available to use in every cell of a spreadsheet.

Compute cost basis of stocks with FIFO method in Google Sheets

Compute cost basis of stocks with FIFO method in Google Sheets

After selling a portion of my holdings in a stock, the cost basis for the remain shares of that stock in my portfolio is not simply the sum of all transactions. When selling, I need to decide which shares I want to sell. One of the most common accounting methods is FIFO (first in, first out), meaning that the shares I bought earliest will be the shares I sell first. As you might already know, I use Google Sheets extensively to manage my stock portfolio investment, but, at the moment of writing this post, I find that Google Sheets does not provide a built-in formula for FIFO. Luckily, with lots of effort, I succeeded in building my own FIFO solution in Google Sheets, and I want to share it on this blog. In this post, I explain how to implement FIFO method in Google Sheets to compute cost basis in stocks investing.
