Frequently Asked Questions
How does it handle merged cells?
Merged cells (colspan/rowspan) are detected and the value is either duplicated across affected cells or represented as a single entry depending on the conversion mode.
What if my table has no headers?
You can specify whether the first row should be treated as headers. If no headers exist, the tool can generate keys like column1, column2, etc.
Can I extract from a full HTML page?
Yes! Paste the entire HTML page source. The tool will find all <table> elements and let you choose which one to convert.
What JSON format is generated?
Typically an array of objects, where each object represents a row with keys from table headers. You can also choose array-of-arrays format.
