INI Validator
Validate INI configuration file syntax and structure. Check for parsing errors, analyze sections and keys, and generate detailed reports. Perfect for debugging configs, pre-conversion validation, and auditing.
Recommended Settings
For Debugging
- •Validate before deploying to production
- •Check error messages for specific syntax issues
- •Use validation to catch malformed sections
For Migration
- •Validate INI before converting to other formats
- •Review section/key counts for completeness
- •Copy report for documentation purposes
Pro Tips
- •Global keys appear before any [section] header
- •Validation doesn't check value formats or types
- •All validation happens client-side for complete privacy

When to Use This Tool
Validate INI configuration files to identify syntax errors, malformed sections, or invalid key-value pairs before deploying to production. Catch parsing issues early to prevent application crashes or configuration errors in production environments.
Recommended: Debugging
Check INI file structure and syntax before converting to JSON, XML, or YAML. Ensure your INI file is properly formatted to avoid conversion errors and data loss. Identify structural issues that might cause problems during format transformation.
Recommended: Data Migration
Analyze INI configuration files to understand their structure, count sections and keys, and generate reports for documentation or compliance. Useful for configuration management, security audits, and maintaining configuration inventories across systems.
Recommended: Auditing
How It Works
Paste your INI configuration file content
Click 'Validate INI' to parse and analyze
Tool attempts to parse the INI syntax
If valid: displays section/key statistics and breakdown
If invalid: shows specific error messages
Copy detailed report for documentation or debugging

Frequently Asked Questions
What does the validator check?
The validator parses your INI file to check for syntax errors, identifies all sections and keys, counts configuration elements, and verifies the overall structure. It detects malformed syntax, invalid section headers, or key-value pair issues that would prevent proper parsing.
What are global keys?
Global keys are key-value pairs that appear before any section header in the INI file. They're placed at the root level of the configuration. For example, 'version=1.0' before the first [section] is a global key. Some INI parsers handle these differently.
Does it validate key/value formats?
The validator checks INI syntax (sections, keys, values) but doesn't validate specific value formats or types. It ensures the file can be parsed correctly but doesn't enforce schema rules like 'port must be a number' or 'email must be valid'.
Can I export the validation report?
Yes! Click 'Copy Report' to copy a formatted text report to your clipboard. The report includes validation status, statistics (section count, key count), a list of all sections with their keys, and any error messages if validation failed.
Is my data safe?
Absolutely! All validation happens entirely in your browser using client-side JavaScript. No data is ever sent to any server, ensuring complete privacy and security for your configuration files.
