Borderlands 3 Savegame Editor

Project description

Borderlands 3 Commandline Savegame/Profile Editor

This project is a commandline Python-based Borderlands 3 Savegame and Profile Editor. It's a companion to the very similar CLI editor for BL2/TPS, and provides some very similar functionality. It can be used to level up your characters, unlock Mayhem modes early in the game, unlock TVHM, add SDUs, unlock equipment slots, and more.

This editor has only been tested on PC Savegames -- other platforms' savegames are not supported at the moment.

Please keep the following in mind:

  • This app does not have any graphical interface. You must be on a commandline in order to use it. (A rudimentary web interface is available, though -- see below.)
  • The app has only very limited item-editing capability at the moment, which is restricted to:
    • Item Levels can be changed
    • Mayhem Level can be set on items
  • It does not offer any direct ability to alter Guardian Rank status.
  • While I have not experienced any data loss with the app, take backups of your savegames before using this, and keep in mind that it could end up corrupting your saves. If you do encounter any data loss problems, please contact me and I'll try to at least fix whatever bug caused it.

Web UI

Abram Hindle is providing a simple web-based version of this utility, so feel free to give that a try:

Yes, this will install python and bl3-cli-saveedit in your browser and give you a tiny UI to dupe your savefiles or import items.


This editor requires Python 3, and has been tested on 3.7, 3.8, 3.9, and 3.10. It also requires the protobuf package.

The easiest way to install this app is via pip/pip3. Once Python 3 is installed, you should be able to run this to install the app:

pip3 install bl3-cli-saveedit

Once installed, there should be a few new commandline utilities available to you. The main editor is bl3-save-edit, and you can see its possible arguments with -h/--help:

bl3-save-edit -h

There's also a bl3-save-info utility which just shows some information about a specified savefile. You can see its possible arguments with -h/--help as well:

bl3-save-info -h

If you've got a raw savegame protobuf file that you've hand-edited (or otherwise processed) that you'd like to import into an existing savegame, you can do that with bl3-save-import-protobuf:

bl3-save-import-protobuf -h

Alternatively, if you've got a savegame exported as JSON that you'd like to import into an existing savegame, you can do that with bl3-save-import-json:

bl3-save-import-json -h

Finally, there's a utility which I'd used to generate my BL3 Savegame Archive Page. This one won't be useful to anyone but me, but you can view its arguments as well, if you like:

bl3-process-archive-saves -h

There are also profile-specific versions of most of those commands, which can be used to edit the main BL3 profile.sav:

bl3-profile-edit -h
bl3-profile-info -h
bl3-profile-import-protobuf -h
bl3-profile-import-json -h


When a new version is available, you can update using pip3 like so:

pip3 install --upgrade bl3-cli-saveedit

You can check your current version by running any of the apps with the -V/--version argument:

bl3-save-info --version

Notes for People Using Windows

This is a command-line utility, which means there's no graphical interface, and you'll have to run it from either a Windows cmd.exe prompt, or presumably running through PowerShell should work, too. The first step is to install Python:

  • The recommended way is to install Python from Grab what's available in the 3.x series (at time of writing, that's 3.9.4), and when it's installing, make sure to check the checkbox which says something like "add to PATH", so that you can run Python from the commandline directly.
  • If you're on Windows 10, you can apparently just type python3 into a command prompt to be taken to the Windows store, where you can install Python with just one click. I've heard reports that this method does not provide the ability to add Python to your system PATH, though, so it's possible that running it would be more complicated.

When it's installed, test that you can run it from the commandline. Open up either cmd.exe or PowerShell, and make sure that you see something like this when you run python -V:

C:\> python -V
Python 3.9.4

If that works, you can then run the pip3 install bl3-cli-saveedit command as mentioned above, and use the commandline scripts to edit to your heart's content.

Running from Github

Alternatively, if you want to download or run the Github version of the app: clone the repository and then install protobuf (you can use pip3 install -r requirements.txt to do so, though a pip3 install protobuf will also work just fine).

You can then run the scripts directly from the Github checkout, though you'll have to use a slightly different syntax. For instance, rather than running bl3-save-edit -h to get help for the main savegame editor, you would run:

python -m bl3save.cli_edit -h

The equivalents for each of the commands are listed in their individual README files, linked below.

Finding Savegames

This app doesn't actually know where your savegames or profiles are located. When you give it a filename, it'll expect that the file lives in your "current" directory, unless the filename includes all its path information. When launching a cmd.exe on Windows, for instance, you'll probably start out in your home directory (C:\Users\username), but your savegames will actually live in a directory more like C:\Users\username\My Documents\My Games\Borderlands 3\Saved\SaveGames\<numbers>\. The easiest way to run the utilities is to just use cd to go into the dir where your saves are (or otherwise launch your commandline in the directory you want). Otherwise, you could copy the save into your main user dir (and then copy back after editing), or even specify the full paths with the filenames.

Editor Usage

For instructions on using the Savegame portions of the editor, see

FOr instructions on using the Profile portions of the editor, see


  • Would anyone appreciate an option to delete Fabricators? Hm.
  • Would be nice to have some anointment-setting functions in here.
  • Did we want a function to clear Vault Card progress?
  • PS4 Support (for already-unlocked saves, anyway)
  • If we fail to read a savefile or profile, might be nice to actually check if it's the other of profile-or-savefile, and give a more helpful message in those cases.
  • Something a bit more Enum-like for various things in; I know that's not very Pythonic, but when dealing with extra-Python data formats, one must sometimes make exceptions.
  • Unit tests?


The encryption/decryption stanzas in BL3Save.__init__ and BL3Save.save_to were helpfully provided by Gibbed (rick 'at' gibbed 'dot' us), so many thanks for that! The protobuf definitions are also provided by Gibbed, from his Borderlands3Protos repo, and used with permission. Gibbed also kindly provided the exact hashing mechanism used to work with weapon skins and trinkets.

The rest of the savegame format was gleaned from 13xforever/Ilya's gvas-converter project:

Abram Hindle is responsible for getting a web version of this utility online (based on his ttwl-cli-saveedit fork for Wonderlands). Thanks!

Many thanks also to Baysix, who endured an awful lot of basic questions about pulling apart item serial numbers. Without their help, we wouldn't have item level editing (or nice item names in the output)!

Basically what I'm saying is that anything remotely "hard" in here is all thanks to lots of other folks. I'm just pasting together all their stuff. Thanks, all!


All code in this project is licensed under the zlib/libpng license. A copy is provided in COPYING.txt.

Other Utilities

Various BL3 Savegame/Profile editors have been popping up, ever since Gibbed released the encryption details. Here's a few which could be more to your liking, if you didn't want to use this one for whatever reason:

A couple others exist but as of September 2022, are out of date and not really great for use on newer saves. Here they are, though, in case they get updated without me noticing:

In Memoriam: Baysix, the author of the original web-based editor at, passed away in early 2021, and that editor is now permanently offline. RIP!

v1.6.1 - June 13, 2020

  • Updated room decoration/trinket/weaponskin alphabetization to ignore case (so "Casino Banner" sorts before "COV Bat," for instance).
  • Counts of unlocked cosmetic items in bl3-profile-info will now include the "default" cosmetics which are always unlocked, so those counts match the numbers in-game.

v1.6.0 - June 11, 2020

  • Updated for extra content introduced by Takedown at the Guardian Breach
  • Added --golden-keys option to bl3-profile-edit, to set available Golden Keys

  • Updated item name mapping to distinguish between the blue-rarity mission reward version of Redistributor from the legendary version from Maliwan Takedown.

v1.5.0 - April 28, 2020

  • Added ability to alter Mayhem level for items, both in savegames and profile. --item-mayhem-max will set items to the max Mayhem level (10), or --item-mayhem-levels <num> will set a specific level (0 to remove Mayhem from items entirely).
  • Item level reports when viewing contents or exporting items will include the Mayhem levels
  • Info views will show the total number of available SDUs along with the purchased count

    • Altering the level of gear stored in the bank
    • Unlocking all global customizations/cosmetics
    • Alphabetizing the list of room decorations, trinkets, and weapon skins
  • Display changes for bl3-save-info - introduced individual arguments to show more detailed information as-requested, instead of only having a global -v/--verbose option:
    • Added -i/--items argument, to show inventory information
    • Added --fast-travel argument, to show unlocked fast travel stations
    • Added --all-challenges argument, to list all challenges in the save file and their statuses (note: this will be over 1.5k items!)
    • Added --all-missions argument, to list all completed missions in addition to active ones
    • -v/--verbose now implies the four options above.
  • bl3-save-info will now also report on whether the savegame has finished the main game or any of the DLCs.
  • Added --unfinish-nvhm option to bl3-save-edit, to completely clear out any TVHM data and pretend that NVHM was never finished.

v1.3.1 - April 14, 2020

  • Bah, forgot a few more README tweaks about the JSON export/import

v1.3.0 - April 14, 2020

v1.2.1 - April 12, 2020

  • Updated Credits section of the README with one more credit that I'd wanted to put in but forgot. :)

v1.2.0 - April 12, 2020

  • Added ability to change item/weapon levels, using --items-to-char or --item-levels
  • Item Imports will now not import Fabricators unless explicitly told to with the --allow-fabricator option.
  • Item names and levels are now shown where appropriate:
    • In verbose bl3-save-info output
    • In item export files
    • While importing items
  • Updated to Protobuf v3, which is what BL3 itself uses. Now when we re-save without any edits, the save should be identical to the original savegame.
  • Item export will now be done without any encryption, so an item will have the exact same item code regardless of where it came from (previously, item codes would change every time the game was saved, so the same item could have very different-looking codes)
  • Added -V/--version flag to show version number

v1.1.1 - April 7, 2020

  • Added in Citizen Science mission name.

v1.1.0 - April 7, 2020

  • Added bl3-save-import-protobuf command, to load a raw protobuf file into an existing savegame.

v1.0.1 - April 5, 2020

  • Some saves include Eridium as an ammo type, presumably related to the Fabricator. Fixed a crash in bl3-save-info related to that.

v1.0.0 - April 5, 2020

  • Initial version
