Generate a Markdown table from JSON objects

Use an array of objects as input and append merge-cell notes for manual Markdown editing

| `quarter` | `sales` | `region` |
| --------- | -------: | -------- |
| Q1        |      120 | APAC     |

Examples

1. Convert CSV to Markdown Table

Technical Writer
Background
A writer needs to include a list of project contributors in a README file based on a CSV export.
Problem
Manually typing out Markdown syntax for a large dataset is error-prone and slow.
How to Use
Paste the CSV data, set the header style to 'Bold', and enable 'Pad Columns' for readability.
Example Config
inputFormat: csv, hasHeader: true, headerStyle: bold, padColumns: true
Outcome
A perfectly aligned, readable Markdown table ready to be pasted into the project documentation.

2. JSON to Markdown with Merge Hints

Developer
Background
A developer is documenting API endpoints and needs to group related parameters.
Problem
Standard tables don't support merging, making it hard to represent grouped data clearly.
How to Use
Input the JSON data, define the merge ranges in the configuration, and enable 'Include Merge Hints'.
Example Config
inputFormat: json, headerStyle: code, mergeRanges: A2:A3 merged as Group 1
Outcome
A clean Markdown table with a footer note explaining how the cells should be logically grouped.
