When to Convert
Common scenarios where this conversion is useful
Python Project Modernization
Upgrade legacy Python projects from pip requirements.txt to modern Poetry dependency management for better reproducibility and easier maintenance.
Dependency Conflict Resolution
Solve complex dependency conflicts by migrating to Poetry's automatic dependency resolver that prevents incompatible package versions.
Development Environment Setup
Streamline team onboarding by converting manual pip install workflows to Poetry's automatic virtual environment and dependency installation.
CI/CD Pipeline Optimization
Improve build reliability by switching from requirements.txt to Poetry's lock files that ensure identical dependency versions across environments.
Package Publishing Workflow
Simplify Python package distribution by consolidating setup.py metadata and requirements.txt into a single pyproject.toml configuration.

Upload your requirements.txt file
Select your requirements.txt file or paste the dependency list directly into the converter. The tool supports all pip requirement formats including version constraints.
-
2
Convert to Poetry format
Click convert to automatically transform pip dependencies into Poetry's pyproject.toml format with proper dependency groups and version specifications.

3
Download pyproject.toml
Save the generated pyproject.toml file to your project root and run 'poetry install' to create a new virtual environment with resolved dependencies.
Frequently Asked Questions
Poetry uses pyproject.toml for unified project configuration, automatic dependency resolution, lock file generation, and built-in virtual environment management, while requirements.txt is just a plain text list of packages.
Yes, the converter maintains your specified version constraints. Exact pins (==1.0.0) become exact versions, while flexible constraints (~=, >=) are converted to Poetry's equivalent syntax.
If you have separate dev-requirements.txt or test-requirements.txt files, convert them separately and the tool will place them in Poetry's [tool.poetry.group.dev.dependencies] section.
Git URLs from requirements.txt (-e git+https://) are converted to Poetry's Git dependency format with proper repository and revision specifications in pyproject.toml.
Yes, Poetry can generate requirements.txt files with 'poetry export --format=requirements.txt' command, though you'll lose Poetry-specific features like dependency groups.
Comments from requirements.txt are preserved where possible, though Poetry's TOML format has different comment syntax. Important notes may need manual review after conversion.
Package extras (package[extra]) from requirements.txt are converted to Poetry's extras syntax, and optional dependencies can be placed in separate dependency groups.
Yes, you'll need Poetry installed on your system. Install it with 'pip install poetry' or use the official installer from poetry.eustace.io before running 'poetry install'.
Python version and platform markers (python_version>=3.8) from requirements.txt are converted to Poetry's marker syntax in the pyproject.toml dependencies section.
The converter handles standard pip formats. Complex cases like local paths, custom indices, or advanced pip features may need manual adjustment in the generated pyproject.toml.
The basic converter focuses on dependencies. You can manually add [tool.poetry] project metadata like name, version, description, and author information to the generated pyproject.toml.
Poetry automatically resolves dependency conflicts, creates reproducible lock files, manages virtual environments, and provides a unified workflow for development, testing, and publishing Python packages.
