Connection String Parser
Parse database connection strings into individual components or build connection URIs from scratch. Supports PostgreSQL, MySQL, MongoDB, Redis, and JDBC — all processing happens locally in your browser.
How ZeroData protects your privacy
- ✓ No Uploads: Processing happens entirely via client-side JavaScript.
- ✓ No Storage: We do not have a database. We physically cannot save your data.
- ✓ No Tracking: We don't log what you process or track your inputs.
- ✓ Verifiable: Check your DevTools Network tab. You will see 0 outbound requests.
Parse Any Database Connection String Instantly
Database connection strings contain your most sensitive infrastructure credentials — hostnames, ports, usernames, and passwords all encoded into a single URI. Pasting these into online tools exposes every credential to a third-party server. This Connection String Parser runs entirely in your browser, so your credentials never leave your device. After extracting components, use our ENV File Formatter to organize them into a clean .env file, or convert them with our ENV to JSON Converter for application configuration.
Connection String Formats Explained
Each database uses a slightly different URI format. PostgreSQL uses postgresql://user:pass@host:5432/db, MySQL uses mysql://user:pass@host:3306/db, MongoDB supports both standard and SRV formats (mongodb+srv://), and Redis uses redis://default:pass@host:6379/0. JDBC strings prefix the driver name: jdbc:postgresql://host:5432/db. This tool automatically detects the format and extracts all components, including query parameters like sslmode, retryWrites, and authentication options. For Docker-based workflows, feed the extracted values into our Docker Compose env_file Mapper to generate proper environment configuration.
How to Use the Connection String Parser
- Paste your database connection string into the input area or select a preset.
- The tool automatically detects the database type and parses all URI components.
- Review the extracted components: host, port, database, username, and parameters.
- Copy generated code snippets for Node.js, Python, or Java.
- Switch to Build mode to construct a new connection string from individual fields.
Common Use Cases
- Extracting database credentials from legacy connection strings during migration.
- Converting connection URIs to individual environment variables for Docker containers.
- Generating boilerplate database client code from a connection string.
- Debugging connection failures by validating URI component formatting.
- Building properly encoded connection strings with special characters in passwords.
Frequently Asked Questions
What database connection strings does this tool support?
This tool supports PostgreSQL (postgres://), MySQL (mysql://), MongoDB (mongodb:// and mongodb+srv://), Redis (redis://), and JDBC formats for PostgreSQL and MySQL. It automatically detects the database type from the URI scheme.
Is it safe to paste my production connection string here?
Yes. This tool runs 100% in your browser using client-side JavaScript. Your connection strings are never sent to any server, stored in any database, or logged anywhere. Verify by checking your browser's Network tab.
Can I build a connection string from individual components?
Yes. Switch to Build mode to enter host, port, database, username, and password separately. The tool generates a properly formatted connection URI that you can copy directly into your application configuration.
What is a JDBC connection string?
JDBC (Java Database Connectivity) connection strings follow the format jdbc:driver://host:port/database and are used by Java applications to connect to databases. This tool parses JDBC strings for both PostgreSQL and MySQL.
How do I convert a connection string to environment variables?
Parse your connection string here to extract individual components (host, port, database, user, password), then use our ENV File Formatter to organize the extracted values into a properly formatted .env file for your application.
