Stop Scrolling Logs: A Privacy-First Log Viewer for JSON, CSV & Raw Logs

Ankit Agrawal — Thu, 05 Feb 2026 11:32:01 +0000

When debugging APIs or production issues, I often need to inspect large JSON responses, CSV exports, or raw log files. Most options involve either writing ad-hoc scripts, loading data into heavyweight tools, or uploading sensitive files to third-party services.

To solve this, I built Log Viewer — a lightweight, client-side log analysis tool that parses JSON, CSV, and unstructured log data directly in the browser and renders it in a searchable, filterable tabular format.

Key characteristics:

Runs entirely client-side (no backend processing)
No authentication or file uploads
No persistence — files are never stored or transmitted
Automatic detection of timestamps, nested JSON, and common log patterns

I’m looking for technical feedback from the community:

Are there additional formats or log schemas worth supporting ?

Any performance or UX improvements you’d expect when working with large files?

Features you typically rely on when inspecting logs or structured data?

The goal is to keep this tool fast, minimal, and privacy-preserving while still being genuinely useful in real debugging workflows.
