Reddit GDPR Export Data Viewer

A modern, standalone offline viewer for your Reddit GDPR data export files.

Data Visualization

View Your History: Browse Posts, Comments, Messages, Saved Items, and Votes in a clean interface.
Analyze Content: See removed or deleted posts that are still in your archives.
Track Activity: Visualize your account statistics and subscription history.

Search & Filter

Global Search: Instantly search across all your reddit data.
Advanced Filtering: Filter by Date Range, Subreddit, or Post Type (Text/Link).
Sorting: Automatically sorted by newest first for easy timeline browsing.

Key Features

Standalone: Single executable logic (requires web files), no installation needed.
Private: Runs 100% locally. Your data never leaves your computer.
Dark Mode: Modern, eye-friendly dark interface.
CSV Support: Natively reads standard Reddit GDPR export CSV files.

Caution

Security Warning: Never run an executable file (.exe) downloaded from the internet without scanning it first. We strongly recommend uploading the RedditViewer.exe to VirusTotal before running it to ensure it's safe.

Requirements

Windows 10 or higher (for executable) OR Node.js 18+ (to run from source)
Your Reddit Data Export (CSV files)

Build from Source

If you prefer to build the executable yourself:

Install Node.js 18+.
Install pkg globally: npm install -g pkg

Run the build command:

pkg server.js --targets node18-win-x64 --output RedditViewer.exe

Installation

Download the latest release and unzip it to a folder (e.g., MyRedditViewer).
Scan RedditViewer.exe with VirusTotal.
Create a folder named csv inside.
Place your Reddit export CSV files (e.g., posts.csv, comments.csv) into the csv folder.
Double-click RedditViewer.exe.
The application will launch automatically in your default browser.

Browser-Only Usage (No Executable)

You can use the application directly in your web browser without the executable:

Open index.html in your web browser.
Drag and drop your CSV files or use the file picker to load your data.
Note: In this mode, nothing is saved when you close the browser. You will need to reload your data each time.

FAQ

Is my data safe?

Yes, absolutely. The viewer runs locally on your machine (localhost). No data is ever uploaded to any server.

Can I run this offline?

Yes. Once you have the application files, you can disconnect from the internet and browse your history freely.

My browser didn't open automatically?

You can manually open your browser and navigate to http://localhost:3000 after running the executable.
