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

AutoSheet

GitHub license npm npm bundle size

Simple library that accepts xls files, applies the transformations you want to them and it returns a csv file with the result.

It works in the browser and node.

Why

I was tired of repeating the same boring steps with the xls files my banks provide. I only needed some columns, with different names and as csv. (I use YNAB to track my spending).

Install

npm install auto-sheet

Usage

Node

const AutoSheet = require("auto-sheet");

function transform(transformations) {
  transformations.deleteRows("1,4-6,8");
  transformations.deleteColumns("C,E-G");
  transformations.renameCell("A1", "DATE");
}

AutoSheet.run({
  transformFn: transform,
  fromFile: "./input.xls",
  toFile: "./output.csv",
});

// Using script
AutoSheet.run({
  transformScript: `
    DELETE ROWS 1,4-6,8
    DELETE COLUMNS C,E-G
    RENAME CELL A1 DATE
  `,
  fromFile: "./input.xls",
  toFile: "./output.csv",
});

Browser

<script src="https://unpkg.com/[email protected]/dist/FileSaver.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/xlsx.js"></script>
<script src="https://unpkg.com/[email protected]/dist/auto-sheet.js"></script>

<input id="xls_file" type="file" name="xls_file" />

<script>
  document
    .getElementById("xls_file")
    .addEventListener("change", handleFileAsync, false);

  async function handleFileAsync(e) {
    const file = e.target.files[0];
    const data = await file.arrayBuffer();
    
    AutoSheet.run({
      transformFn: transform,
      from: data,
      toFile: "out.csv",
    });
    
    AutoSheet.run({
      transformScript: `
        DELETE ROWS 1,4-6,8
        DELETE COLUMNS C,E-G
        RENAME CELL A1 DATE
      `,
      from: data,
      toFile: "out-2.csv",
    });
  }

  function transform(transformations) {
    transformations.deleteRows("1,4-6,8");
    transformations.deleteColumns("C,E-G");
    transformations.renameCell("A1", "DATE");
  }
</script>
