Hello Saeed,
I am well versed with Excel and can help on this. I checked the Excel file you have attached so there are multiple columns with column AH having the sizes. While I will merge the size column, how you would like other columns to be formatted, a quick discussion would help.
I am well versed with Excel and its various features like Userforms, Pivot tables, HLookup, Vlookup, Countif, SUMIF, Left, Right, Index Match, drop down, filters, charts, graphs, conditional formatting, mail merge, dashboards and can provide the Excel that you are looking for.
If need be I can also do automation using VBA/Macros.
Looking forward to your response.
Thanks
