How to get a JSON wallet from MetaMask

Unfortunately, MetaMask does not support the option to export your key in JSON format. The following guide will show you a workaround on how to do it.

Step 1

Go on the MetaMask browser extension and click the three-dotted settings icon.

Click on ‘Export Private Key’, confirm with your password and ‘Export as file’. You will download your private key as a CSV file.

  x/(x+1) - (x+1)/(x+2)
= (x+2)x/(x+1)(x+2) - (x+1)(x+1)/(x+1)(x+2)
= ((x^2 + 2x) - (x^2 + 2x + 1))/(x+1)(x+2)
= 1/(x+1)(x+2)
