Extract text from network log files (HAR)
To convert HAR network logs to another format, you need Chrome DevTools or other Developer software.
To convert other file formats to the "HTTP Archive Log File" file type, you need software like Chrome DevTools or a similar tool.
A .HAR file is an HTTP Archive network log, structured natively as a JSON document. It records detailed interactions between a web browser and a website. Developers and IT support teams generate these files using the developer tools in browsers like Google Chrome or proxy tools like Charles Proxy and Fiddler to troubleshoot performance bottlenecks, failing API calls, and rendering issues.
Despite their usefulness, raw .HAR files present significant disadvantages. Because they rely on verbose JSON structures, they are nearly impossible for a human to read directly in a standard text editor. They also suffer from severe file bloat; a simple browsing session can produce a file exceeding 100MB if large assets or base64 images are logged. Most critically, .HAR files are notorious security liabilities. They capture plain-text payloads, which means they routinely expose active session cookies, authentication tokens, and user passwords.
Converting .HAR files is essential for safe sharing and effective analysis. For spreadsheet analysis and reporting, convert to CSV. For extracting strictly the payload data without the bloated metadata, convert to optimized JSON. For archiving audit trails, convert to .PDF/A.
Convert.Guru analyzes your HAR file, detects the exact format, and lets you read the text inside.
Users also converted JSON, TXT, JMX, COM, LOG, PDF, CUSTOMIZATION, CHLS, CHAR, ZIP, HRL, SAZ and HSR files.
If you want to convert HAR file to JMX, CSV, JSON, PDF, TXT, CURL, HTML, HTM, CSS, JS, PHP or ASP, you can use Chrome DevTools or similar software from the "Network Request Logging" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to HAR, try Chrome DevTools or another comparable tool in the "Network Request Logging" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HAR converter.
