The converter creates a column for every unique key found across all objects. Objects missing a key get an empty cell in that column.

Yes. Switch between comma, semicolon, and tab delimiters from the options. Use semicolon for European Excel versions that treat commas as decimal separators.

CSV is a text format, so all values become strings. Numbers and booleans are written without quotes but will be re-typed by the spreadsheet application when opened.

There is no hard limit. JSON arrays with thousands of objects are converted without issues.
