I wanted to share my personal experience. I was working on a file for the last three years, and I update it every Friday. Yesterday, when I was updating it, it closed automatically. When I tried to open it, I got the same error message.
I tried to open that file in different ways but, I couldn't open it. I don't have a backup. Huh, a panic situation.
I have read around 100 forums and tried many solutions, but none of them worked for me. I discussed with my Sr. and decided to purchase software to handle this error. I have downloaded five tools: Stellar Excel repair, Recovery toolbox, online office recovery, systools excel and, Kernel excel repair.
Select my file and tried to repair it. Systools, kernel, and office recovery software didn't detect the file, and I got the error. Now, I tried Stellar Excel, which successfully accepted the file for repairing and started recovery. After completion of the restoration, I checked the preview. I saw my 95% data in preview, but 5% was missing. Then, I tried recovery toolbox, it also repairs 95% data, but, the formatting was not proper, so, I gave preference to Stellar Excel repair software.
I successfully purchased it and repaired my file. I fixed my 95% data, but I am happy to get my data back and took a backup of it. If you want to give a try this utility then check official site: https://www.stellarinfo.com/repair-excel-file.php

Hi LeonPatter23 , we want to help you with your question, but we need more information from you. Can you please add details in the comment box? what version of excel are you running and what version is the file you are trying to open ?
