Question 1

How do I use the JSON to Table Converter?

Accepted Answer

Paste your JSON array (a list of objects in square brackets) into the input field, and the tool automatically builds a table with one row per object and column headers from the keys.

Question 2

Which JSON structure works best for tables?

Accepted Answer

An array of objects is ideal: each object becomes a row and shared keys become columns. A single object is also supported and renders as a one-row table.

Question 3

How are nested objects handled?

Accepted Answer

The tool flattens nested objects, expanding sub-keys like address.city into separate columns using dot notation, so deeply nested data stays readable in a flat table.

Question 4

What output formats can I get?

Accepted Answer

You can copy or download the resulting table as HTML, Markdown, or CSV, making it ready to drop into a web page, documentation, or a spreadsheet.

Question 5

How do I open the CSV output in Excel?

Accepted Answer

Download the CSV and open it in Excel or Google Sheets; if special characters look off, choose UTF-8 encoding during import to keep them intact.

Question 6

What happens if objects have different keys?

Accepted Answer

The tool uses the union of all keys across objects as columns, and any field missing from a given object is left blank in that row, so no data is dropped.

Question 7

Where can I use the Markdown output?

Accepted Answer

Paste the Markdown table into a GitHub README, documentation, or a notes app; the row and column separators are generated automatically, so no manual alignment is needed.

Question 8

Why isn't my table rendering?

Accepted Answer

The most common cause is invalid JSON: a missing comma, single quotes instead of double quotes, or an unclosed bracket. Make sure your input is valid JSON starting with an array or object.
