Import your emojis

1. We need to install this extension
2. Go to https://slack.com/customize/emoji and select your slack workspace
3. We just drag the emojis folder in Bulk Emoji Uploader section

download.sh

mkdir -p emojis;

for emoji_line in $(cat emojis.csv); do
  name=$(echo "$emoji_line" | cut -d, -f1)
  url=$(echo "$emoji_line" | cut -d, -f2)

  curl -s -o "emojis/${name}" "${url}"
done

saveEmojisToExcel.js

// grab slack custom emoji URLs and save as CSV

let emojis = {};

// get auth token for API request
let teams = JSON.parse(localStorage.localConfig_v2).teams
let slackId = window.location.pathname.split('/')[2] // or you can put directly your slack id
let authToken = teams[slackId].token;

// setup request
let formData = new FormData();
formData.append('token', authToken);

(async () => {
  let rawResponse = await fetch('/api/emoji.list', {
    method: 'POST',
    body: formData
  });

  let emojisApi = await rawResponse.json();
  
  emojis = emojisApi.emoji;
  
  // generate CSV
  var csvContent = 'data:text/csv;charset=utf-8,';

  for (const [name, url] of Object.entries(emojis)) {
    if (typeof url === 'string' && url.startsWith('http')) {
      let filename = name.replace("'", "\\'") + '.' + url.split('.').pop();

      csvContent += filename + ',' + url + '\n';
    }
  }

  // download csv
  let encodedUri = encodeURI(csvContent);

  let csvDownloader = document.createElement('a');
  csvDownloader.href = encodedUri;
  csvDownloader.download = 'emojis.csv';

  document.body.appendChild(csvDownloader);
  csvDownloader.click();
  document.body.removeChild(csvDownloader);
})();

i=0; for f in *; do d=dir_$(printf %03d $((i/25+1))); mkdir -p $d; mv "$f" $d; let i++; done
