Frequently Asked Questions
Are my JSON files or sensitive API payloads uploaded to a server? ↓
No. Like all tools on UtilsConsole, this converter runs 100% client-side in your web browser. Your JSON data, credentials, and customer records never leave your local machine.
How does this tool handle nested JSON objects and arrays? ↓
You can enable "Flatten Nested Objects" to automatically unroll deep properties into flattened columns (e.g. `user.address.city` or `user_address_city`). If flattening is disabled, nested objects and arrays are neatly serialized into JSON strings.
Which Excel formats are supported? ↓
You can download native OpenXML Excel workbooks (.xlsx) that open directly in Microsoft Excel, Google Sheets, Apple Numbers, and LibreOffice Calc. You can also export Excel XML Spreadsheet (.xls) or copy TSV data to paste directly into open spreadsheets.
Can I format the Markdown table output? ↓
Yes. You can customize column alignment (Left, Center, Right, or Auto-detect numbers), toggle monospace padding for clean reading, and pipes `|` or newlines within cell values are properly escaped.
What types of JSON structures are accepted? ↓
The converter accepts arrays of objects, single objects, key-value maps, arrays of arrays, and wrapped API payloads (such as `{ data: [...] }` or `{ items: [...] }`).
