About Arslan Malik
Arslan Malik is a software engineer who builds and maintains jsontoexcel.net. He wrote the conversion engine behind the tool, including the flattening logic that turns deeply nested JSON objects and arrays into usable spreadsheet columns. He writes about JSON, Excel, and the practical problems that come up when moving data between the two.
Why I built this tool
I kept hitting the same problem at work: an API would return a few thousand rows of nested JSON, and the person who actually needed the data wanted it in a spreadsheet. The existing options all had the same catch — install something, sign up for something, or upload the file to someone else's server. None of that is acceptable when the data is a customer export.
So the converter runs entirely in your browser. The JSON never leaves your machine. The part that took the longest to get right was flattening: deciding how a nested object three levels deep, or an array of objects with inconsistent keys, should become columns that a human can actually read. That logic is the reason this tool exists rather than being a thin wrapper around a library.
How I write these guides
Every method described on this blog is one I have run myself before publishing it. Code samples are tested, and version-specific steps (Power Query menus, for example) are written against the version named in the article. If something has drifted out of date or is simply wrong, I would rather hear about it than leave it up — email support@jsontoexcel.net and I will correct it.
