HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
const dataArray = [];

for (let i = 0; i < 1000; i++) {
  const subArray = [];
  const numSubparts = Math.floor(Math.random() * 5) + 1;
  
  for (let j = 0; j < numSubparts; j++) {
    const len = Math.floor(Math.random() * 100) + 1;
    let str = '';
    for (let k = 0; k < len; k++) {
      str += chars[Math.floor(Math.random() * chars.length)];
    }
    subArray.push(str);
  }
  
  dataArray.push(subArray);
}

// Format 1: JSON string
const jsonData = JSON.stringify(dataArray);

// Format 2: Double-delimited string
const splitData = dataArray.map(arr => arr.join(';')).join(',');

Tests:

Json
/*When writing async/deferred tests, use `deferred.resolve()` to mark test as done*/ JSON.parse(jsonData)
Text
splitData.split(',').map(p => p.split(';'))
