The tool creates a column for every unique property found across all features. Features that lack a particular property have an empty cell in that column.

Yes. Download the CSV and open it in Excel. If you encounter encoding issues with non-ASCII characters, import the file using Excel's data import wizard with UTF-8 encoding.

You can go back from CSV to GeoJSON using the CSV to GeoJSON tool, but you would need to rejoin the geometry data separately if it was not included in the CSV.

There is no hard limit. FeatureCollections with thousands of features are exported without issues.
