Frequently Asked Questions

How are duplicate header names handled?

If "Use First Row as Headers" is enabled and there are duplicate names in the header row, the tool will attempt to make them unique by appending a counter (e.g., `headerName`, `headerName_1`). If a header cell is empty, a generic name like `columnN` will be used.

What happens to `colspan` and `rowspan`?

The current version of the parser simplifies `colspan` and `rowspan`. The content of a spanned cell will typically be associated with the first logical cell/header in the span. For complex nested structures or precise span handling, the JSON output might not perfectly represent the visual layout.
