Excel CSV export encoding
Solution 1:
I have found a blog post which outlines an Applescript solution to a similar problem. I've adapted it to your needs. Note that I haven't done any proper quoting of cell values or anything, it will need some tweaking to be more robust. It's also not the fastest solution in my minimal testing… but it's a start.
The key is write X to openFile as «class utf8»
tell application "Microsoft Excel"
activate
set outFile to (path of active workbook)
set fileName to (name of active workbook)
set outFile to (outFile & ":" & fileName & ".csv")
set openFile to open for access file outFile with write permission
set eof openFile to 0
set lastCol to count of columns of used range of active sheet
set lastRow to count of rows of used range of active sheet
repeat with r from 1 to lastRow
set rowStr to (value of cell r of column 1 of active sheet)
repeat with c from 2 to lastCol
set cellVal to (value of cell r of column c of active sheet)
set rowStr to rowStr & "," & cellVal
end repeat
write rowStr & return to openFile as «class utf8»
end repeat
close access openFile
end tell
Solution 2:
I found the easiest thing to do was to just let excel export to csv in its own dumb way, then open up a terminal and do the following:
iconv -t UTF8 -f MACROMAN < file.csv > file-utf8.csv
