Hi,
Where can I find some plugin which convert files ods (LibreOffice) or xls (Microsoft Office) to redmine table?

For now, I and my friends are using my own tool (https://www.s2rc.miszczyk.dev) but it is very old (about 4 years) and built-in option or plugin would be much better.

Currently my tool only supports:

• Calculating formulas ( for example: "=sum(A7:K17)" )
• Merged cells
• Bold font
• Italic font
• Font color
• Background color
• Text aligning (left/center/right)

I would be nice if built-in option or plugin create the same output or better.

Output from my tool using xls file (converted from ods file in LibreOffice) :
