Extract Text from JSON
Extract all textual strings from nested JSON objects and arrays. Perfect for localization, translation workflows, and corpus analysis.
Step-by-Step Instructions
Paste or Upload JSON Data
Paste JSON objects, arrays, or API payloads into the editor.
Specify Target Key or Extraction Mode
Choose to extract all string values across the entire JSON tree or specify a target key name (e.g., 'title', 'email', 'body').
Configure Output Formatting
Choose output format: Line-by-Line list, comma-separated values (CSV), or clean text block.
Copy or Download Extracted Text
Copy the extracted text values directly into your documents, spreadsheets, or training datasets.
Key Features & Capabilities
- Recursive JSON tree traversal extracting string values from deeply nested objects and arrays
- Key-targeted extraction (extract all values matching specific property keys e.g., `text`, `comment`, `description`)
- Duplicate elimination filter removing repeated string values
- JSONPath and dot-notation path extraction support (`users[*].profile.bio`)
Frequently Asked Questions
How does key-targeted text extraction work in JSON?
When you specify a target key (e.g., `message`), the extractor performs a depth-first search across all nested objects and arrays in the JSON hierarchy, extracting every value paired with the `message` key while ignoring all other metadata.
Can this tool extract emails or URLs from complex API JSON payloads?
Yes. By targeting keys like `email` or `url` (or using full tree extraction with regex filters), you can extract all email addresses or URLs from massive multi-megabyte API response dumps into a clean list in seconds.
How does the tool handle non-string JSON data types (numbers, booleans, null)?
You can configure the extractor to extract only string values or convert numeric and boolean values to text strings during traversal.
Is large JSON file extraction processed client-side?
Yes. The extractor uses recursive JavaScript memory iteration locally in your browser. No JSON files, API responses, or database records are ever uploaded to an external server.
