Text to JSON

The tool converts plain text into JSON by applying two simple modes. In array mode, each non-empty line becomes a separate string element in a JSON array. In key-value mode, lines containing a colon are parsed as properties and assembled into a JSON object. Example: input 'apple\\nbanana' yields [\"apple\",\"banana\"]. Input 'name: Alice\\nage: 30' yields {\"name\":\"Alice\",\"age\":\"30\"}.
Core logic and behavior: It trims whitespace, splits by newline, and applies the selected mode. It outputs a JSON string that can be compact or pretty-printed. It preserves line content for string values and converts key/value pairs into object members. Validation ensures UTF-8 text and deterministic results, enabling reliable data exchange.
Inputs & Outputs: Inputs: input_text (string), mode (string: 'array' or 'keyval'), pretty_print (boolean). Outputs: json_output (string), and an indicator for pretty formatting. Empty input yields an empty array; lines with no colon are ignored in key-value mode and non-empty lines become strings in array mode.
Algorithms & Calculations: Steps: trim input_text, split by newline, for array mode collect non-empty lines as strings; for keyval mode parse lines containing a colon as key/value pairs, otherwise treat as strings or ignore invalid lines; assemble into array or object; apply pretty printing if requested; produce a valid JSON string.
Error & Edge Cases: Empty input yields an empty array; lines without colon in key-value mode are ignored; lines with multiple colons are split at the first colon; very long lines are preserved unless a max_lines limit is set; if parsing fails, the tool returns an empty JSON structure in API contexts.
Industry/Region & Localization: UTF-8 text handling; language-neutral line endings; suitable for en-us workflows; no currency or date inference.
Assumptions & Exclusions: Assumes simple line-based formats; does not infer nested structures beyond one level; excludes complex natural language parsing, multi-field schemas, or semantic data interpretation; no UI or networking behavior described.
