            Bug ID: 109003
           Summary: Feature request: Auto filling cells by example /
                    context of neighbouring cells, aka "Flash Fill"
           Product: LibreOffice
           Version: 5.3.4.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: gerry.treppel at googlemail.com

Please add a feature to Calc that auto-fills cells based on context of
neighbouring cells and examples of correct entries by the user. Spreadsheet
cell content usually follows a certain pattern and it is a frequent use case
that part of this pattern is needed for further analysis in other cells. 

LibreOffice Calc should be able to automatically extract/autofill the relevant
piece of the neigbouring cell content based on examples entered by the user. 

Example 1: I want to fill the last name in column B based on the full name in
column A.

COLUMN A                                COLUMN B
Bjoern Michaelsen                       Bjoern
Armin le Grand                          Armin
Katarina Behrens                        Katarina
András Timár                            ?
Michael Meeks                           ?
Tomaž Vajngerl                          ?
Caolan McNamara                         ?
I give three examples and expect Calc to fill the remaining cells in column B
correctly based on my example.


Example 2: I want to fill the first character of the last name in column B
based on the full name in column A.

COLUMN A                                COLUMN B
Bjoern Michaelsen                       M.
Armin le Grand                          G.
Katarina Behrens                        B.
András Timár                            ?
Michael Meeks                           ?
Tomaž Vajngerl                          ?
Caolan McNamara                         ?
I give three examples and expect Calc to fill the remaining cells in column B
correctly based on my example.


Example 3: I have variable names which follow a certain pattern in column A and
I want to extract the middle part for column B:

COLUMN A                                COLUMN B
aw16_treatA_total                       treatA
ch28_ebsoZ_total                        ebsoZ
adi43_treatZ_other                      treatZ
ch45_treatAA_beso                       ?
zh123_midA_total                        ?
ph45_midZZ_other                        ?
sdi345_treatT_total                     ?
I give three examples and expect Calc to fill the remaining cells in column B
correctly based on my example.


The requested enhancement corresponds to the "Flash Fill" feature introduced
with MS Excel 2013. For more information, see:
