Frequently Asked Questions

It transforms structured JSON data into the INI format commonly used in configuration files. Top-level JSON objects become [sections], nested objects are flattened with dot-notation keys, and arrays are either converted to comma-separated lists or kept as JSON strings.

Yes. Deeply nested objects are expressed using dot notation (e.g., database.host=localhost). Sections are created only from top‑level object values, keeping the output clean and readable.

Simple arrays (numbers, strings) become comma-separated values. Complex arrays of objects are stored as compact JSON strings. You can easily edit them later and convert back using the Swap feature.

Absolutely. Click the Swap button to reverse the direction. Paste your INI content into the left panel and hit Convert to obtain a JSON representation. The converter automatically detects section headers and global properties.

Yes. When converting from INI to JSON, lines starting with ; or # are treated as comments and ignored. The converter also recognizes inline comments and strips them during parsing.
