MatchError when Parsing XLSX
barakyo opened this issue · comments
Hi!
Thanks for the great library. We're using this in production and noticed that we're having an error when trying to parse XLSX files whose columns may be missing some style information (for example a column with no values). The error seems to go away when we directly delete that that column.
This is the error we get:
(MatchError) no match of right hand side value: []

I've attached the spreadsheet, missing_styles.xlsx, where this occurs.
As a heads up, I have a fix for this, but I thought it would better to log an issue and open a PR which fixes this.
