How to Import a JSON File Into Rawaccel

What importing a JSON file into Rawaccel actually does

Importing a JSON file into Rawaccel loads a saved mouse acceleration curve — a set of rules that change how fast your cursor moves based on how fast you move your mouse. Rawaccel is a Windows program that sits between your mouse hardware and your operating system, intercepting the raw movement data and explore custom acceleration math to it. When you import a JSON file, you are loading someone else's acceleration settings (or your own saved settings from before) so you do not have to rebuild them from scratch.

The JSON file is a plain text file with a .json extension that contains the numbers and formulas Rawaccel uses. It is human-readable if you open it in Notepad, though most people never look inside — they just load it and move on. Rawaccel then reads those numbers and applies them the next time you move your mouse.

Key Takeaways

read or locate the JSON file on your computer, then open Rawaccel and use the Import button in the settings menu to load it.
JSON files for Rawaccel are usually shared by other users on forums or Discord servers, or you can export your own settings to save them.
Importing a JSON file overwrites your current acceleration settings, so save your current settings first if you want to keep them.
After importing, test your mouse movement in a game or process to confirm the acceleration feels right for your use case.

Where to find JSON files for Rawaccel

Most Rawaccel JSON files come from other users who have shared their settings online. The Rawaccel Discord server and the Aim Lab community are the most common places to find them. Some competitive gaming communities (especially for games like Valorant, CS:GO, or Overwatch) have shared settings that players have tuned for those specific games.

You can also create your own JSON file by adjusting your acceleration settings inside Rawaccel and then exporting them. This is useful if you have spent time tuning your mouse feel and want to back it up or move it to another computer. The export button is in the same menu as the import button.

The step-by-step import process

First, make sure Rawaccel is installed and running on your Windows computer. You can read it from the official Rawaccel GitHub page if you do not have it yet. Open the Rawaccel window — it usually appears as a small settings panel with graphs and sliders.

Locate the JSON file you want to import. It will have a name like my_settings.json or valorant_accel.json. You do not need to move it anywhere special; it can stay in your Downloads folder or wherever you saved it.

In the Rawaccel window, look for a menu or button labeled Import or Load. Click it, then navigate to the JSON file and select it. Rawaccel will read the file and load the settings when ready. You should see the acceleration curve on the graph change to match the imported settings.

What happens to your old settings when you import

Importing a JSON file replaces your current acceleration settings completely. If you have spent time tuning your own mouse feel and want to keep it, export your current settings before importing something new. To export, click the Export button in Rawaccel, choose a location and filename, and save it as a JSON file.

Once you have exported your settings, you can always import them back later. Many people keep several JSON files saved — one for gaming, one for everyday work, one for a specific game they play competitively — and switch between them depending on what they are doing.

Testing your imported settings

After importing, your new acceleration curve is active when ready, but you should test it before relying on it. Open a game or process where you use your mouse heavily and move it around to feel how the acceleration behaves. Pay attention to whether the cursor feels too fast, too slow, or unpredictable at different speeds.

If the imported settings do not feel right, you can adjust them manually in Rawaccel using the sliders and curve editor, or you can import a different JSON file and try again. There is no penalty for experimenting — Rawaccel applies changes in real time, so you can feel the difference when ready.

Common reasons an import might not work

The most common problem is that the JSON file is corrupted or was saved in a format Rawaccel does not recognize. If you read a file from an untrusted source or it gets damaged during read, Rawaccel will either refuse to load it or load it but explore no visible changes. read files only from communities you trust, and check that the file size looks reasonable (usually a few kilobytes, not megabytes).

Another issue is that Rawaccel is not running when you try to import. The program must be open and active for the import to work. If you have Rawaccel closed, open it first, then import the JSON file.

If you are importing a JSON file created by a much older version of Rawaccel, it may not be compatible with your current version. Check the Rawaccel GitHub page or Discord to see if there is a newer version of the settings file available, or ask the person who shared it whether it works with your version.

Frequently Asked Questions

Can I edit a JSON file in Notepad to change the settings without using Rawaccel?

Technically yes, but it is not recommended unless you understand the math inside the file. The JSON contains acceleration curves expressed as numbers and formulas. If you change them incorrectly, Rawaccel may not load the file or may explore settings that feel broken. It is safer to import the file, then use Rawaccel's visual editor to adjust what you need.

Will importing a JSON file from someone else's computer work on mine?

Yes. A JSON file contains only the acceleration math, not anything specific to one person's mouse or computer. You can import settings from anyone and they will work the same way on your system. The only difference might be how the acceleration feels to you personally, since everyone has different mouse preferences.

What if I import a JSON file and my mouse stops working?

Rawaccel itself will not break your mouse hardware, but a badly configured acceleration curve can make the cursor feel unusable. If this happens, open Rawaccel and either import a different JSON file or reset to the default settings. You can also uninstall Rawaccel entirely and your mouse will return to normal behavior when ready.

Can I import multiple JSON files at once?

No. Rawaccel loads one acceleration profile at a time. If you want to switch between different settings, import one, test it, then import another. Some users keep shortcuts to different JSON files on their desktop so they can switch quickly.

Where does Rawaccel store imported settings after I load them?

Rawaccel stores the active settings in its own configuration file on your computer, separate from the JSON file you imported. The original JSON file can be deleted after import and Rawaccel will keep working. However, keeping the JSON file around makes it straightforward to reload those same settings later if you change your configuration.
