Apache Access Log Parser
Parse Apache or NGINX combined-format access log lines into structured fields: client IP, timestamp, request, status code, response size, referrer and user agent.
About this tool
Parse Apache or NGINX combined-format access log lines into structured fields: client IP, timestamp, request, status code, response size, referrer and user agent.
Example
Input: 127.0.0.1 ... "GET /x" 200 2326
Output: IP: 127.0.0.1 | Request: GET /x | Status: 200
Privacy
This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.
How to use this tool
- Paste one Apache or NGINX combined-format access log line into the input box.
- Check that the line includes the client IP, timestamp, request, status code, size, referrer, and user agent.
- Run the parser to convert the raw line into separate fields.
- Copy the structured result into your editor, spreadsheet, or script.
Step by step, what happens
- The tool reads the log line as plain text and looks for the combined access log layout.
- It splits the line into structured fields such as client IP, timestamp, request, status code, response size, referrer, and user agent.
- If the line matches the expected format, it returns a parsed record that is easier to inspect or reuse.
- If a field is missing or the line is not in combined format, the parser may not extract every value correctly.
Worked example
Here is a typical combined-format Apache access log line for a request to the home page.
Input: 127.0.0.1 - - [10/Oct/2000:13:55:36 -0700] "GET /index.html HTTP/1.0" 200 2326 "http://www.example.com/start.html" "Mozilla/4.08 [en] (Win98; I ;Nav)"
- The parser reads the IP address, timestamp, request, status code, and response size from the log line.
- It also captures the referrer and user agent from the quoted fields at the end.
- The tool returns the line in structured form so each part can be copied or processed separately.
Output: client_ip: 127.0.0.1
timestamp: 10/Oct/2000:13:55:36 -0700
request: GET /index.html HTTP/1.0
status_code: 200
response_size: 2326
referrer: http://www.example.com/start.html
user_agent: Mozilla/4.08 [en] (Win98; I ;Nav)
Tips and common mistakes
- Use a full combined log line, because the parser expects the referrer and user agent fields to be present.
- Keep the quotes around the request, referrer, and user agent exactly as they appear in the log.
- If your server uses a custom log format, it may not parse correctly unless it matches Apache or NGINX combined format.
- Make sure the timestamp stays in the same bracketed format, including the timezone offset.
