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

n8n-nodes-spreadapi

This is an n8n community node for SpreadAPI — it lets you run spreadsheet calculations as part of your n8n workflows.

SpreadAPI turns Excel models into web APIs: pick cells as inputs and outputs, publish, and every calculation your spreadsheet can do becomes callable — pricing models, financial calculators, engineering formulas, quotes.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation:

Settings → Community Nodes → Install and enter n8n-nodes-spreadapi.

Operations

Calculate

Sends input values to a published SpreadAPI service and returns the calculated outputs. Runs once per incoming item — to calculate many scenarios, feed the node many items.

  • Inputs — a typed form generated live from the service definition: fields with allowed values become dropdowns, booleans become toggles, numbers get number inputs, and required fields are enforced. Switch to JSON mode to map a whole object from a previous node instead.
  • Simplify Output (default on) — outputs arrive as a flat object, e.g. { "monthly_payment": 1265.79, "total_interest": 155684.4 }. Turn it off for the raw API response including metadata.
  • Bypass Cache — force a fresh calculation.

Get Service Details

Returns the service's full self-description: input parameters (types, ranges, allowed values), outputs, and usage documentation. Useful for exploring a service or building dynamic workflows.

Credentials

One paste is all it takes: copy the service URL from your service's Integration panel (n8n section) and paste it into the credential's Service URL field. For token-protected services the URL already includes the token; for public services the plain URL works. n8n tests the connection when you save the credential.

In the node, pick your service From List (it shows the credential's service) — the input form then loads automatically. For public services you can skip the credential and choose the service By URL or By ID.

Things to know

  • Percentages are decimals. A rate of 5% is 0.05, not 5. Strings like "5%" are converted automatically.
  • Numbers and booleans given as text are converted server-side; yes/no, true/false and 1/0 all work for boolean inputs.
  • Validation errors name the exact parameter, what's wrong, and the allowed values — check the error output when a calculation fails.
  • The Service ID is shown in the service's Integration panel and in its URL.
