Merge files in Windows cmd & Power Shell

Windows cmd

cmd /c 'copy /y /b *.json output.json' 

Windows Power Shell

2 options are here:

Get-Content *.json | Set-Content result.json
Copy-Item *.json output.json

How to wrap joined lines into valid JSON

After merging json files we append commas to the end of each line and bracket around the whole content with [ ] using eg. Notepadd++ for that. Thus we get a valid JSON:

[
{ "Full Year Tax":"145,26$"… },
{ "Full Year Tax":"139,00$"… },
{ "Full Year Tax":"100,00$"… }
]

Static Residential Proxies

We’ve alsredy spoke of Rotating Residential Proxies but now I want to share SmartProxy‘s new Static Residential Proxies.

Static Residential Proxies do not rotate randomly but rather on-demand. They are good for web scraping to make a spider maintain its session at single website. And this session memory might last for life.

How are they different from dynamic/rotating residential proxies?

  • Greater stability
  • Faster speed
  • Website sessions keeping

When it comes to scrapping websites, captchas and other type of
protections were always the main obstacle in providing reliable data collection solutions. And most often this would lead to consider bypass services which aren’t always free.
