Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@sheetxl/formulas

A modern, type-safe library of spreadsheet functions, ready for any JavaScript or TypeScript project.

@sheetxl/formulas is the official open-source function library for SheetXL. It is designed to be robust, easy to use, and compatible with popular spreadsheet applications.

Our Philosophy

This library has a simple goal: to create a comprehensive set of spreadsheet functions written in TypeScript.

Our implementation is heavily inspired by and derived from the great work done on formulajs. We are deeply grateful for their contribution to the community and aim to build upon that foundation with a modern, type-safe architecture.

Our plan is to support the complete function sets of Microsoft Excel and Google Sheets, while also embracing new and useful functions suggested by the community.

Key Features

  • Comprehensive: Growing support for Math, Text, Logical, Financial, and Lookup functions.
  • TypeScript First: Written from the ground up in TypeScript for robust type safety.
  • Vector Optimized: Functions are designed to leverage the vector API of @sheetxl/primitives, allowing them to efficiently operate on ranges of data (IRange), not just single values.
  • Engine-Agnostic & Lightweight: A simple TypeScript API with no spreadsheet engine dependency. Its only core dependency is @sheetxl/primitives.
  • Permissively Licensed: Free to use for any project under the MIT license.

Installation

# Using npm
npm install @sheetxl/formulas @sheetxl/primitives

# Using pnpm
pnpm add @sheetxl/formulas @sheetxl/primitives
