Hey RayRay, Thanks for this, it was super helpful with my project. I had one small issue with \r being inserted into my column 2 keys and values which sounds like it was the same as Mohd. Here was my solution: const csvArray = csvToArr(e.target.result, "," ); csvArray. value = JSON.stringify(csvArray, null, 2 ).replaceAll( "\\r" , "" ); Simply just use replaceAll to remove the '\r's. There is probably a nicer way to do that, but this is good enough for me. Thanks again. Bryon
