使用正则表达式清理JSON字符串

const string = '{"ECommerce ":{" Shopify ":," Magento ":," WooCommerce ":," Squarespace ":},"Tools ":{" Grunt ":," Gulp ":," Vagrant ":},"Containers ":{" LXC ":," Docker ":," Rocket ":},"Digital ":{" SEO ":," Email Marketing ":," Inbound Marketing ":," Crowdfunding ":," Content Distribution ":," Display Advertising ":," Ad Planning and Buying ":," Article Writing ":," SEM ":," Customer Relationship Management ":," Viral Marketing ":," Market Research ":," Social Media ":," Affiliate Marketing ":," Lead Generation ":},"Performance ":{" LoadStorm ":," httperf ":," JMeter ":," LoadUI ":," Blazemeter ":," LoadImpact ":," Nouvola ":," LoadRunner ":," Soasta CloudTest ":},';

const json = string
  .replace(/ /g, '') // remove excess spaces
  .replace(/(?!^){/g, '[') // replace braces (except the first) with brackets
  .replace(/}/g, ']') // replace closing braces with brackets
  .replace(/:]/g, ']') // remove erroneous colons before brackets
  .replace(/:,/g, ',') // remove erroneous colons before commas
  .replace(/.$/, '}'); // replace last comma with bracket

console.log(JSON.parse(json));
