Frequently Asked Questions (FAQ)
Is this JSON to Table converter safe to use?
Yes, absolutely! Our table generator is 100% secure because all processing happens entirely in your browser using client-side JavaScript. Your data never leaves your device - it's never uploaded to our servers or transmitted anywhere. This means your sensitive data remains completely private and secure.
What is JSON and why would I convert it to a table?
JSON (JavaScript Object Notation) is a popular data format used by APIs and web applications. It's great for storing structured data but not easy to read in its raw form. Converting JSON to HTML tables makes the data human-readable and perfect for presentations, documentation, or web pages. If your JSON isn't formatted correctly, try our JSON Formatter tool first.
What is CSV and how does delimiter detection work?
CSV (Comma-Separated Values) is a simple file format used by spreadsheet applications like Excel and Google Sheets. Our tool automatically detects common delimiters including commas (,), semicolons (;), tabs, and pipes (|). You can also manually override the detection if your data uses an unusual delimiter or if auto-detection fails.
Can I create a responsive HTML table?
Yes! The generated HTML code is clean and semantic, making it easy to add responsive styles. You can wrap the table in a container with CSS like overflow-x: auto to make it horizontally scrollable on mobile devices. Our generated CSS includes responsive-friendly base styles that work well across all screen sizes.
Is there a limit to the data size I can process?
The only limit is your browser's available memory. Our tool efficiently processes most typical datasets without issues - we've successfully tested it with thousands of rows and dozens of columns. For very large datasets (10,000+ rows), we recommend using the pagination feature to improve performance and user experience.
How do I handle nested JSON data?
For nested JSON objects, use the JSON Path feature to specify the path to your data array. For example, if your data is nested like {"data": {"results": [...]}}, enter "data.results" in the JSON Path field. This tells the tool exactly where to find your table data within the JSON structure.
Can I add sorting and search functionality to my table?
Absolutely! Check the "Sortable columns", "Search/filter box", or "Pagination" options to automatically generate the necessary HTML and JavaScript code. The generated code includes everything needed for these interactive features to work - just copy and paste it into your website or application.
What output formats are supported?
We provide three output formats: clean HTML code for websites, complete CSS for styling, and Markdown tables for documentation platforms like GitHub, GitLab, and Notion. Each format includes copy-to-clipboard functionality and download options. The Markdown format is particularly useful for README files and technical documentation.
