Log2Curl
Convert any copied API log into a ready-to-use cURL command.
Log2Curl reads raw HTTP request logs from your clipboard and generates a valid curl command you can run in a terminal or share with your team. It works with logs from Flutter, Laravel, Node.js, Nginx, and generic HTTP clients—no manual copy-pasting of URLs, headers, or bodies.
Features
- Framework-agnostic — Supports Flutter/Dart, Laravel/PHP, Node/NestJS, Nginx reverse-proxy logs, and generic HTTP logs.
- Smart extraction — Infers URL (full URL, base+path, or host+path), HTTP method, Authorization token, custom headers, and request body from unstructured text.
- Semantic body detection — Identifies the request body using labels (e.g.
REQUEST BODY/DATA:, request_body="...") and key analysis, not “last {} block.”
- Log-style JSON → valid JSON — Normalizes unquoted keys, unquoted values, and empty fields so broken log output becomes valid JSON for
--data.
- Custom headers — Parses non-JSON header sections (e.g.
HEADERS: followed by Key: Value lines) and adds them to the cURL command.
- Offline & cross-platform — No network calls; runs on macOS, Windows, and Linux.
How to Use
- Copy raw API logs from your app, server logs, or debug console.
- Open the Command Palette:
Cmd+Shift+P (macOS) or Ctrl+Shift+P (Windows/Linux).
- Run “Log → Convert to cURL”.
- The generated cURL is copied to your clipboard. Paste it into a terminal to run the request.
If the clipboard is unavailable (e.g. some remote setups), the extension opens the cURL in a new editor tab instead.

What Log2Curl extracts |
| Flutter |
FULL URL:, BASE URL: + PATH:, POST REQUEST DETAILS, HEADERS: (line-by-line), REQUEST BODY/DATA: |
| Laravel / PHP |
Full URL, method, token, body from JSON or log-style blocks |
| Node / NestJS |
Method, URL, body; log prefixes stripped |
| Nginx / logfmt |
host=... + path from request line, request_body="{...}", authorization="Bearer ..." |
| Generic HTTP |
First http(s):// URL, method from request line or labels, body from balanced {} blocks |
- URL — Prefers labeled
FULL URL: or REQUEST URL:; otherwise base URL + path, or first http(s):// URL, or host + path from request line.
- HTTP method — From
Method: POST, POST REQUEST DETAILS, POST /api HTTP/1.1, or framework hints (postRequest, http.post, axios.post, etc.). If none found, you can pick from a list.
- Authorization — From
Authorization: Bearer ..., user token ..., or authorization="Bearer ...".
- Custom headers — From a
HEADERS: (or HEADER:) section with Key: Value lines.
- Request body — From labeled body/data sections, logfmt
request_body="...", or the highest-scoring {...} block (excluding headers/metadata).
Requirements
- VS Code
^1.105.0 (or Cursor / compatible editor).
- No extra dependencies or network access; the extension runs fully offline.
Extension Settings
Log2Curl does not add any configurable settings. It uses the clipboard and the single command “Log → Convert to cURL.”
Known Issues
- Very large logs (e.g. huge JSON bodies) may slow parsing; consider trimming the pasted text to the relevant request.
- Multi-line unquoted values in log-style bodies are parsed up to the next structural delimiter (comma,
}, newline); complex edge cases may need manual tweaking.
Release Notes
0.0.1
- Initial release.
- URL extraction (full URL, base+path, host+path).
- HTTP method inference (explicit + framework hints).
- Token extraction (Bearer, user token, access_token).
- Semantic body extraction (logfmt, balanced-brace scoring, body markers).
- Custom headers from
HEADERS: section (Flutter-style logs).
- Body normalization (log-style → valid JSON).
- cURL generation with optional
--data and custom headers.
- Clipboard copy with fallback to new tab when clipboard is unavailable.
- Top-level error handling to avoid extension host crashes.
