Saved me years of data.

I have a crucial numbers file with 13 years of data and which I had not backed up in 2 years (yes that was really stupid on my part) - and recently my computer crashed while in the spread sheet. It corrupted the file to where no program could open it. I tried online conversions - I tried everything - even trying to hire some to save it. After a week of non stop trying to fix it, Today I discovered Hex Fiend and I was able to access the file - fix the corruption and get my data back (I now have multiple copeis of the file and will be backing up religiously on a daily basis from now on). Thanks to the dev(s) of Hex Fiend - you saved my bacon.

I am reviewing version 2.14.1 (available on the Hex Fiend web site) running on Monterey. This is a *great* tool. Currently I use it more for for examining files than for editing. For me the most interesting feature is the binary template feature to overlay the file contents with structure. I've been using it to learn about Bitcoin blockchain structure examining Bitcoin Core blockchain files. The feature implements a Tcl interface. (Yeah, I know, there are plenty of tools around to examine the BTC block chain.) The UI is mature and clean compared to some other free editors I've used. Highly recommended.

Indispensable Hex Editor for Forensics

HexFiend has been an indispensable tool for me for years now, and its value has only increased since I'm involved in more forensics work as of late. This open-source hex editor for macOS impresses with its speed and versatility. It effortlessly handles even massive 30 GB files, a feat that's crucial in forensic investigations, and without excessive memory use. One of its standout features are binary templates, which make it easy to see file structure. Whether dissecting file systems or uncovering hidden data, HexFiend remains my go-to! Many thanks to the developers.

I rarely have to edit binary files and can usually get away with built-in tools when I do, but this time really needed to do only and exactly what this tool does: Unambiguously and directly edit the hex in-place. Thanks!
