Turn off auto-replace

You’ll find a load of options at Tools -> ‘AutoCorrect Options…’. If you want to turn off all auto-replacement then browse around the tabs and disable/enable most things.

Here are the ones that bother me the most…


Do the following prevent hyphens being auto-replaced with a dash character:

  1. Tools -> AutoCorrect Options…
  2. Untick ‘Replace dashes’.

Date contractions

Do the following to stop date contractions 1st, 2nd, 3rd, 4th etc being auto-replaced with superscript st, nd, rd or th:

  1. Tools -> AutoCorrect Options…
  2. Localized Options tab.
  3. Untick ‘Format ordinal numbers suffixes (1st -> 1^st)’.

Filter column to find unique cells

If the sheet has a lot of data e.g. 30000 rows then select a column or row otherwise the whole sheet will be auto selected and the app will slow to the point of despair.

Standard filter

Select column. Data -> Filter -> Standard Filter…

Condition <> empty Options -> No duplications

Advanced filter

I did this first before I found that a standard filter could be easier / faster. I’ve left this here for future reference, at which point I’ll review.

Data -> Filter -> Advanced Filter..

Set a range e.g. $N1:$N32324 Options -> No duplications.

Performance is shit with large sheets. Also I would get ‘This range does not contain a valid query’ errors randomly, even if I used the mouse to select a range!

Advanced filter


If you have a condition like SUMIF, you must use double quotes. Single quotes won’t work.


If you use single quotes you’ll get a sum of 0.

Source cell range from different sheet

  1. Copy the range in sheet 1.
  2. Paste Special in sheet 2, selecting the Link option.

Show rows hidden by a filter

If you apply a filter and it hides a load of cells, select all cells (i.e. selection includes cells before and after), then do Format -> Row -> Show.

Export a graph/chart

One way of exporting a spreadsheet graph or chart is to copy it into a LibreOffice drawing and export from there.

  1. Copy the chart to the clipboard.
  2. Create a new drawing. File -> New -> Drawing.
  3. Paste into the drawing.
  4. Export the drawing (as whatever format you want).

Flip a bar chart

If you have a bar chart that shows largest to smallest and you want it to show smallest to largest…

  1. Right-click the chart and select Edit.
  2. Right-click on the labels of the axis you’d like to flip and select Format Axis.
  3. On the Scale tab select ‘Reverse direction’.
  4. Click OK.

Weird characters that look like Chinese

If you open a document and it contains a single cell with odd characters (e.g. 慲獮捡楴湯ⱳⰬⰬਬ堬塘⁘塘) then you probably need to open the file again and select the correct encoding.

On linux you can determine the encoding of a file as follows:

test@pc ~ $ file -bi example.csv
text/plain; charset=utf-8
