Text to JSON Converter Online

Use this free Text to JSON Converter to turn common text formats into structured JSON that is easier to read, copy, download and use in development workflows. It supports line-based arrays, key-value text, escaped string output and CSV-style rows, so you can choose the format that matches your source data.

Convert TXT and Plain Text to JSON

If you have a TXT file, copied notes, a list of values, configuration-style entries or simple exported data, paste the text into the converter and select the appropriate parsing mode. The tool is useful for preparing data for JavaScript, APIs, test fixtures, configuration work and other applications that accept JSON.

Key Features

  • Convert lines into a JSON string array.
  • Convert key:value or key=value text into JSON objects.
  • Convert CSV-style rows into JSON objects.
  • Create an escaped JSON string from raw text.
  • Choose 2-space, 4-space or minified JSON formatting.
  • Review JSON validity before copying or downloading the result.
  • Browser-based processing for supported text input.

Useful for Developers, Data Cleanup and API Work

A text to JSON converter can help when moving simple text data into a web application, preparing sample JSON for an API request, creating test data, cleaning copied lists, or turning basic CSV-style rows into structured records. For complex CSV files with quoted commas, embedded line breaks or advanced escaping, use a dedicated CSV parser and review the generated JSON before importing it.

Can I convert key-value text to JSON?
Yes. Key-Value mode supports lines using a colon or equals sign and converts the supported pairs into a JSON object.

How to Use the Text to JSON Converter

  1. Paste your plain text, line list, key-value entries or CSV-style data.
  2. Select the parsing format that matches the input.
  3. Choose the JSON indentation you want to use.
  4. Review the validation status and generated JSON.
  5. Copy the JSON or download it as a JSON file.

Choose the Right Parsing Mode

Lines as String Array is useful when each non-empty line should become one JSON array item. Key-Value Pairs is intended for simple entries such as name: John or active=true. Escaped String Literal keeps the complete input as one JSON string. CSV Rows is intended for basic comma- or tab-separated rows with a header.

Review Before Using the JSON

Always review generated JSON before importing it into an API, database, application or production workflow. Plain text does not always contain enough information to infer a complete schema, and complex CSV data may require a dedicated parser.
