const name = str.substring(0, 45).trim() // 7-Zip 22.01 (x64)
const id = str.substring(45, 90).trim() // 7zip.7zip

    如果提供的示例具有大部分或所有输入选项，并且只需要前三列，则以下可能有效：

    const TXT = document.querySelector('textarea').value;

const REX = /(?<name>[^.]+)\s+?(?<id>\S+)\s+?(?<version>\S+).+?$/imu;

TXT.split('\n').forEach(row => {
  let {name, id, version} = row.match(REX).groups;
  console.log(`name "${name.trim()}", id "${id}", version "${version}"`);
})
