It's also country specific.
I work on Excel library and the text to number/date feature was one of less fun things to implement at least semi-correctly.
I remember my comment on the PR back then:
https://github.com/ClosedXML/ClosedXML/pull/1899
Like others, I recommend using the ImportExcel module. It uses and wraps EPPlus Software (EPPlus - Create advanced Excel spreadsheets using .NET (GitHub Project Old / New)) which is a DLL that is included with the ImportExcel PowerShell Module.
Project mention: Show HN: My Go SQLite driver did poorly on a benchmark, so I fixed it | news.ycombinator.com | 2023-12-14The meat of the P/Invoke code is in here: https://github.com/electroly/sqlnotebook/tree/master/src/Sql...
The parent directory includes code that uses it. I'm most proud of this SQLite virtual table module that proxies queries to remote ADO.NET connections, allowing you to write joins directly between local SQLite tables and remote SQL Server tables. https://github.com/electroly/sqlnotebook/blob/master/src/Sql...
I've also got a generic virtual table module that lets me easily write table-valued functions in C#: https://github.com/electroly/sqlnotebook/blob/master/src/Sql...
The goal is to provide various "supercharged" features to base SQLite by taking advantage of all the extension points I can. I wish some went further; in particular the virtual table API doesn't "push down" enough of the original query to allow the module to avoid doing O(N+1) queries in some cases.
