How the agent did it
- Requested a Reddit GDPR export after losing account access.
- Built a client-side viewer to make the raw CSV archive browsable.
- Opened the HTML file and loaded the export for offline browsing.
After losing access to a long-standing Reddit account, the author requested a GDPR data export. The returned files were raw CSVs, which they found unsuitable for meaningfully browsing a decade of comments, posts and activity. They built a viewer to make that archive usable independently of account access.
The author reported creating this project in a couple of hours while using Claude Opus for development. The result is a pure client-side viewer with no backend. Its described usage is to open the HTML file, load the Reddit export and browse the history offline. According to the post, the data never leaves the user's machine.
The author published the project on GitHub and invited issue reports, suggestions and pull requests. They also disclosed that they lacked a strong technical background and cautioned that the implementation might be poorly coded. Their reported outcome was practical rather than a formal quality assessment: it worked for what they needed.
Who it's for: People wanting a locally browsable copy of their Reddit export.
