Strava Activity Data Extractor Bookmarklet

Overview

The Strava Activity Data Extractor is a JavaScript bookmarklet designed to extract detailed activity data from a Strava Activity webpage and copy it to the clipboard in JSON format. It also opens a new window displaying the extracted data.

Features

• Extracts activity details, weather data, statistics, and segment efforts from the webpage.
• Copies the extracted data to the clipboard in JSON format.
• Opens a new window displaying the extracted data.

Usage

1. Create a new bookmark in your browser.

2. Edit the bookmark and paste the following code into the URL field:

   javascript:(function(){
       function extractData() {
           function safeGet(selector, property = 'innerText', fallback = 'N/A', context = document) {
               const element = context.querySelector(selector);
               return element ? element[property].trim() : fallback;
           }
   
           function getTableData(selector) {
               const table = document.querySelector(selector);
               if (!table) return {};
               const rows = table.querySelectorAll('tr');
               const data = {};
               rows.forEach(row => {
                   const th = row.querySelector('th');
                   const tds = row.querySelectorAll('td');
                   if (th && tds.length > 0) {
                       const key = th.innerText.trim();
                       if (tds.length === 1) {
                           data[key] = tds[0].innerText.trim();
                       } else if (tds.length >= 2) {
                           data[key] = {
                               avg: tds[0].innerText.trim(),
                               max: tds[1].innerText.trim()
                           };
                       }
