By

I have a data-entry script which adds records to a plain-text data table. It's a fairly complicated script with a GUI dialog, and until recently it added one record at a time. To add another record, I had to launch the script again. Was there a simple way (I asked myself) to re-run the script, or…

On dates and stuffed non-dates

By

Nothing gives my wife the Screaming Meemies like dates in spreadsheets. Unless she formats the target cell in advance as text, the spreadsheet will turn a perfectly innocent, non-date string like 23/2/6 into '23-Feb-2006'. When she types 6420-11-3, according to both LibreOffice Calc and Gnumeric,…

The header line: how to add, delete and ignore it

By

In a plain-text table, the first or header line usually contains the names of the fields. In this article I've pulled together a variety of ways to add and delete a header, and also how to do things with the rest of the table while leaving the header intact as the first line in the file. Add a…

By

If you just love making 'top 10'-type lists but are a little embarrassed to say so, tell people you're passionate about data exploration.

ODT to TXT, but keep the line numbering

By

The title explains what this article is about. If you save an .odt file as text, or copy/paste the contents as a text file, or run odt2txt or the unoconv utility, you lose the apparent line structure of the original, and with it the line numbering. But there is a way... Losing apparent line…
