How does Text to JSON handle key-value pairs?

In Key-Value mode, lines separated by colons (`key: value`) or equals signs (`key = value`) are automatically split into object keys and values with typed numbers and booleans.

Can I convert a simple text list into a JSON string array?

Yes! Switch to 'Line by Line' mode to convert every newline in your text into an element of a JSON array `["item1", "item2"]`.

Why Structure Text Data into Standard JSON?

Unstructured plain text logs, configuration lines, and scrape outputs are difficult for automated APIs to ingest. JSON (JavaScript Object Notation) is the worldwide lingua franca for web services, NoSQL databases (MongoDB, DynamoDB), and frontend applications.

Supported Parsing Modes

Line-by-Line Array: Transforms individual strings separated by newlines into a JSON array (["apple", "banana", "cherry"]).
Key-Value Properties: Parses configuration files like host: localhost or port = 8080 into structured object properties.
CSV / Tabular: Reads header rows and generates an array of structured JSON objects.
Text Payload Wrapper: Encapsulates raw multiline text into an object with metadata like character count and timestamp.

Frequently Asked Questions

Does the converter convert numeric strings to true numbers?

Yes! When "Infer numbers & booleans" is checked, values like "42" or "true" are parsed as numbers and booleans rather than raw strings.

Is any text stored on external servers?

No. Everything operates entirely in your local browser window.
