Data export and import between databases and spreadsheets should be an easy task, but sometimes progress in time doesn't mean advance of products or functionalities, at least it is true fact when we are speaking about Microsoft products.
For instance, a task like specify a separator symbol in Excel; different than comma was so easy in the past, but now it is nightmare.

| Dbvisualizer - find drivers |
Database extraction
For example SQLTools or DB visualizer
-
SQLTools, fast and free tool, can work without installation but requires Oracle client installed.
Config of connections:
.\GNU\SQLTools\connections.xml
or
.\SQLTools\SharedData\connections.xml
-
DB visualizer supports many database drivers (even can be detected from the computer)
Support extraction to CSV files, and select a separator symbol.
Remove Newline Character. Always checked, to avoid return carriage ia a field being used as delimiter
C:\Users\myuser\.dbvis\config70\dbvis.xml
Notes: There is an issue with DBvisualizer/Gnumeric, default windows enconding "cp1252" from DBvis cannot be recognized by Gnumeric.

Ms. Excel 2003
Can import csv, and even specify delimiters but it is useless for exportation to csv as it always delimit columns using semicolon.
Theorically from Computer, regional settings, delimiter can be configured but it doesn´t work.
Ms. Excel (>2007)
Last versions removed the option Import in Menu, so now it is not very intuitive, but it can be done opening a text file with a .txt extension (don't use csv, because automatically comma will be used as delimiter) and a wizards will be launched.
Theoretically from Computer, regional settings, delimiter can be configured but it doesn't work with Windows 7. Probably excel is one of the best Microsoft apps but there is a complete lack of interoperability. Better to use Libreoffice

| Excel import |
Formating contents in Excel:
Cleaning acents:
Limited by maximun of nested functions:
=
SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B1,"á","a"),"é","e"),"í","i"),"ó","o"),"ú","u"),"ã","a")
Convert to Proper name and clean acents
=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(
PROPER(A9),"á","a"),"é","e"),"í","i"),"ó","o"),"ú","u")
Look for a string in an array a extract a column from same row
=
VLOOKUP(b2,!equivalencias$1:$20,2,FALSE)
=VLOOKUP(stringtofind,in_array!$first_row:$last_row,col_to extract,FALSE)
False=match exact string
Find a string in the last characters
=
IF(RIGHT(E2,10)="@domain.es","Spanish",IF(RIGHT(E2,13)="@domain.co.uk","British","none"))
Detect white spaces at beginning or end of a string
i.e if space found write the string without spaces.
=IF(OR(LEFT(A2,1)=" ",RIGHT(A2,1)=" "),TRIM(A2),"Word is OK")
Libreoffice/OpenOffice
Import, just open a csv file and wizard automatically will open.
Export, Save as: CSV with checkbox "Edit filter settings" let us to change delimiter character or add quotation marks to fields
