Export more than 90 days of tweet activity data from https://analytics.twitter.com

export-analytics.js

function exportData(start, end){

  const checkTimer = setInterval(async () => {
    const resp = await fetch(`${document.URL}/export.json?start_time=${start}&end_time=${end}&lang=en&export_type=by_tweet`, {
      method: "post"
    })

    const json = await resp.json()

    if(json.status === 'Available'){
      clearInterval(checkTimer)
      return download()
    }

    console.log(`Export not ready, status ${json.status}`)
  }, 2000)

  async function download(){
    const resp = await fetch(`${document.URL}/bundle?start_time=${start}&end_time=${end}&lang=en&export_type=by_tweet`)
    const blob = await resp.blob()
    const a = document.createElement("a")

    a.href = URL.createObjectURL(blob)
    a.download = `tweet_activity_${start}_${end}.csv`
    document.body.appendChild(a)

    a.click()
  }

}

Go to twitter analytics, click on tweets, press f12 on your keyboard, paste the exportData function into the console tab press enter. Then call the function by pasting
exportData(Date.now(), Date.now() - ((24*60*60*1000) * 200)) (to export 200 days) and pressing enter.

Tested it up to 365 days and worked fine. But it takes some time until the file is ready for download.
You will see a bunch of Export not ready, status Pending until the download is initiated.
