Short answer
How do I turn User-Agent strings into JSON?
Your agent uses the parse_ua tool to break down raw strings into structured objects. You'll get organized data containing browser, OS, and device details. This breakdown shows you exactly what your agent produces.
Data outcomes
Where your data lands.
The AI converts raw log entries into these specific formats.
STRUCTURED
Clean JSON objects
The agent uses parse_ua to output valid JSON. You get a predictable schema for every string you feed it.
IDENTIFIED
Device and OS details
The AI extracts the specific operating system and hardware type. This makes it easy to see what devices your users actually use.
FILTERED
Browser intelligence
The agent pulls out the browser name and version. You can use this to spot outdated clients or specific bot traffic.
HUMAN
Manual review needed
The AI cannot fix broken or malformed strings. You'll need to check any logs that don't follow standard formats.
The workflow
What your AI does when the logs arrive.
The agent handles the heavy lifting of string manipulation so you don't have to write regex.
Receive raw strings
You provide the messy User-Agent lines from your access logs to the agent.
parse_uaDeconstruct the string
The agent runs the parse_ua tool to isolate the browser, engine, and device info.
parse_uaFormat as JSON
The agent organizes the extracted pieces into a structured JSON object.
parse_uaDeliver results
The agent presents the structured data back to you in your chat interface.

How this task behaves.
- 01
Can the AI fix a completely broken User-Agent string?
No. The tool parses existing data; it cannot repair or guess information that isn't present in the string.
- 02
Will the AI change my original log files?
No. The agent only reads the strings you provide. It has no permission to modify or delete your local files.
- 03
What kind of output do I get?
You get structured JSON objects containing the browser, version, operating system, and device type.
- 04
Can I parse thousands of lines at once?
Yes, as long as you provide the data within the context limits of your AI client.
- 05
Does this work with any log format?
The tool specifically targets User-Agent strings. You should extract the string from your log line before asking the agent to parse it.
