Evaluate JSON Converter Tool before you buy

Use the free trial to check whether the result fits your task. Here is what to look for when testing your own data.

  1. Select JSON, NDJSON, or AI export archive

    Open your raw JSON file, nested array, or AI chat transcript (ChatGPT, Claude, WhatsApp). The streaming parser analyzes schema structure in milliseconds.

  2. Configure schema un-nesting & PII masking

    Select output columns, map nested keys into relational columns, and enable automated PII redaction for emails, phones, and API credentials.

  3. Verify spreadsheet or document output

    Export directly to XLSX, CSV, SQL, PDF, or DOCX. The free evaluation converts the first 50 records per object to verify table formatting.

JSON Converter Tool: frequently asked questions

All 6 technical & workflow FAQs
Does Prism JSON Converter Tool send my data to external cloud servers?

No. File parsing and format conversion run locally on your workstation without transmitting your files or converted records over the internet. License verification requires an online check during activation, with manual offline activation available upon request.

How does the tool handle deeply nested JSON objects and arrays?

The flattener recursively traverses nested dictionaries and objects up to 10 levels deep, transforming hierarchical paths into clean column headers using dot notation. Arrays of primitive values are cleanly joined with configurable delimiters, and arrays of objects are budgeted into structured rows.

Can I convert ChatGPT or Claude AI export archives?

Yes. Prism JSON Converter automatically detects AI conversational export formats from ChatGPT, Claude, Gemini, Grok, and Meta AI. It maps nested dialogue trees into chronological user and assistant transcripts, allowing you to export them into formatted PDF, Word DOCX, Markdown, or tabular CSV/Excel files.

What are the limitations of the free evaluation trial?

The free evaluation trial allows you to import JSON files, explore the full hierarchical tree, inspect the flattened preview table, and export up to 50 items per folder (50 records per file) across core formats to evaluate schema mapping and output formatting before licensing.

What is the maximum file size supported?

Prism JSON Converter supports JSON, JSONL, and NDJSON files up to 100MB per file in batch mode. The streaming line-by-line parser handles large files smoothly without memory exhaustion.

Is the software compatible with Section 508 keyboard accessibility standards?

Yes. The application is keyboard operable with visible focus rings, roving tabindex table navigation, arrow-key cycling across preview tabs and format cards, and background-inert accessible modal dialogs complying with Section 508 and WCAG 2.2 AA standards.
