Row ranges are not supported

[igor-savin-ht]

According to Excel documentation, '1:1' is a valid range that returns entire first row. However, js-xlsx only supports ranges of format 'A1-B1'

@igor-savin-ht the helper functions currently assume two-cell ranges. Can you share a file with row or column ranges in a place that causes import errors?

[igor-savin-ht]

@reviewher Yes, that's what I mean - helper functions only support two-cell ranges. I don't think this is file-specific (I observe same behavior on all xlsx files, no matter how simple), and there are no import errors, it's just that if you pass '1:1' range, you always get empty result.

Libs is not supported this feature yet or this is a bug ?
