INI to JSON: Drag Legacy Config Into the Modern Stack

September 12, 2026

A decade-old deployment still has an INI file with sections and keys, and the new service wants a JSON config. Reinventing section parsing in a script is a day of work for a five-minute conversion.

Paste the INI sections and keys and it produces a JSON object. The section names become keys, so most of the structure maps directly with no interpretation layer needed.
