The task of converting JSON to an Excel CSV file won’t take a long time. We suspect it can take less than a minute if you move fast enough and have the relevant knowledge.

If you have a JSON file, you need dedicated software to open or view the JSON file. At times, we need to convert a JSON file into different formats, like the xlsx.

Click "File," "Open" and browse to your second Excel file. Double-click the file to open it. Repeat the steps for each new file you'd like to open in its own window.

That shouldn't be a problem, after all, Excel can handle JSON. So, you try to open the file in Excel using its data import tooling, which usually works very well indeed as a basic ETL system.
