xlsx:get-number-format error with missing tag numFmt
At work, an application is generating an Excel document without the numFmt(s?) tag(s?) in the styles.xml file. Unfortunately, When calling readsheet, the function get-number-format generate an error.
This does not prevent Excel or OpenOffice from opening the document and displaying the cells content correctly, though.
The document contains essentially strings, date and time values, everything in one sheet.
So, shouldn't, the function get-number-format also silently ignore the missing tags and return a default value. Another possibility, could be to allow instructing the library about a strictness level to enforce.
