What Sets This HAR to CSV Converter Apart?
Speed and clarity are baked into every interaction. Unlike hosted converters that upload logs to a remote server, this tool processes HAR files entirely in your browser. The lightweight, Kadence-inspired layout keeps focus on what matters: revealing problematic network requests, isolating third-party drift, and exporting the slices of data your stakeholders demand. Developers, SEOs, CRO teams, and product managers can all use the same interface, swap presets, and export reports without leaving the page.
A dynamic filter matrix helps you surface the exact subset of requests you need. Search by keyword, clamp down to a single hostname, target blocked or failing requests, or spot excessive payloads at a glance. Columns are fully customizable, and presets stay in sync thanks to shareable URLs that encode both filters and visible fields. That means your QA team and your performance engineer can collaborate on identical datasets in seconds.
Because the converter runs client-side, it easily handles enterprise-scale logs without hitting upload limits. Advanced clipboard support, CSV downloads, and quick-reset controls ensure the experience feels as polished as Kadence-powered landing pages, while avoiding the bloat found in most competitors.
How to Use the Converter Effectively
Start by dropping a HAR export from Chrome, Firefox, Edge, or any Chromium-based browser. If your audit tool produces raw HAR JSON, paste it directly into the text area. Click Parse HAR to populate the summary metrics, live preview, and filter controls. Use the preset buttons to jump into common workflows: Performance highlights large transfer sizes and latency. Audit mode surfaces status codes, initiators, and payloads. Minimal mode keeps the CSV lean for spreadsheet pivots.
Refine the dataset with the Focus Filters. The domain filter zeroes in on third parties; method and status filters untangle API behavior; size and performance filters spotlight bloated or sluggish requests. Once dialed in, download or copy the CSV to ship insights into analytics suites, JIRA tickets, or client decks. Use the preset link to reduce repetitive configuration across teams.
