Question 1

What is a HAR file?

Accepted Answer

A HAR (HTTP Archive) file is a JSON-formatted file that records all network requests made by a web browser. It contains detailed information about each HTTP request and response, including URLs, headers, timing data, and response content.

Question 2

How do I create a HAR file?

Accepted Answer

In Chrome: Open DevTools (F12), go to Network tab, perform the actions you want to record, right-click on the requests list, and select 'Save all as HAR with content'. In Firefox: Open DevTools, go to Network tab, right-click and select 'Save All As HAR'.

Question 3

Is my data secure with HAR Explorer?

Accepted Answer

Yes, HAR Explorer processes all data entirely in your browser. No data is ever uploaded to any server. Your HAR files remain completely private and secure on your device.

Question 4

What can I analyze with HAR Explorer?

Accepted Answer

HAR Explorer lets you analyze request timings, identify performance bottlenecks, detect duplicate requests, view headers and cookies, analyze third-party impact, check for mixed content issues, and export filtered data for documentation or sharing.

Question 5

Can I convert HAR files to API documentation?

Accepted Answer

Yes! HAR Explorer can generate beautifully structured API documentation from HAR files. It automatically analyzes response schemas, extracts request/response examples, catalogs endpoints, and creates comprehensive API documentation. This is perfect for documenting APIs by capturing network traffic.

Question 6

What export formats does HAR Explorer support?

Accepted Answer

HAR Explorer supports multiple export formats: (1) API Documentation with automatic schema analysis, (2) Markdown format for documentation and reports, (3) Plain text format for easy sharing, and (4) Filtered HAR files containing only selected requests. All exports can include bookmarked entries and filtered data.

Question 7

How does the response schema analyzer work?

Accepted Answer

The response schema analyzer automatically inspects JSON responses in your HAR file, detects data types, identifies nested structures, and generates structured schema documentation. This makes it easy to understand API response formats and create accurate API documentation without manual analysis.

Question 8

Can I export HAR to Markdown?

Accepted Answer

Yes, HAR Explorer can convert HAR files to Markdown format. The export includes request URLs, methods, status codes, headers, timings, and response data in a well-formatted Markdown document, perfect for technical documentation, bug reports, or sharing with team members.

Question 9

Can I convert HAR to OpenAPI specification?

Accepted Answer

Yes! HAR Explorer can convert HAR files to OpenAPI 3.0 specifications. The converter analyzes your API endpoints, generates schemas from request/response data, and creates a standards-compliant OpenAPI spec. You can then import it into Swagger Editor, Postman, or use OpenAPI Generator to create client SDKs. This works for both individual API endpoints and bulk exports with endpoint deduplication.

Question 10

What are the benefits of OpenAPI export?

Accepted Answer

OpenAPI (formerly Swagger) is the industry standard for API documentation. By converting HAR to OpenAPI, you can: (1) Generate interactive API documentation with Swagger UI, (2) Create client SDKs automatically with OpenAPI Generator, (3) Import specs into Postman for API testing, (4) Enable IDE integration and code generation, (5) Share standardized API specifications with your team, (6) Use with popular API management and documentation tools.

Question 11

Can I export all requests or just unique endpoints?

Accepted Answer

HAR Explorer offers flexible OpenAPI export options. You can enable 'Unique Endpoints' mode to deduplicate and merge similar API calls into clean endpoint definitions with merged schemas, or disable it to export every individual request as separate operations. You can also select which specific endpoints to include in the export using the sidebar.

Question 12

How does HAR Explorer handle API schemas in OpenAPI export?

Accepted Answer

When exporting to OpenAPI, HAR Explorer automatically analyzes request and response payloads to generate JSON schemas. It detects data types, identifies nested structures, recognizes special formats (UUID, email, date, etc.), and merges schemas from multiple requests to create comprehensive endpoint definitions. This means your OpenAPI spec includes accurate request/response schema definitions without manual work.

Question 13

What information is included in the OpenAPI export?

Accepted Answer

HAR Explorer's OpenAPI export includes: (1) Complete endpoint paths and HTTP methods, (2) Operation IDs and tags for organization, (3) Path parameters and query parameters, (4) Request body schemas with data types, (5) Response schemas for different status codes, (6) Server URLs extracted from your HAR file, (7) Parameter descriptions and examples from actual requests.
