GAS – Google Sheets – Dynamic Menu and Functions for Sheet Selection

May seem like a sledgehammer to crack a nut, but I was looking for a way to satisfy two things:

  1. Change sheet tabs and know (script-wise) which tab I had come from and was going to
  2. Create a dynamic menu for sheet tab selection, so that I could get the user focused on a single tab, as opposed to having them all there along the bottom

I first tackled this the hard coded long winded way, capturing the names of all sheets and writing an individual function for each, then moved on the a pair forwards / backwards functions, using “getSheets()” to provide the sheet array. This then lead me to going all dynamic!

Started searching, and there were a couple of posts about placing parameters into custom menu items, but nothing that really cracked it, until I came upon this post:

http://clav.cz/google-apps-script-menu-functions-with-parameters/

where Václav Novotný provides a solution to create a dynamic custom menu, and dynamic scripting for functions to go with it. This was setup for a Google Doc, so I need to rework it a bit for my needs. All credit to Václav Novotný though for the meat on the bones. Continue reading

GAS – Google Sheets – Query All Columns with a Script

Came across a problem using query on a table, where I wanted to query all the columns. No easy way to write this into a function if you have 10 + columns, so set about writing a google apps script to handle this. The premise is simple enough, a data table with a list of people’s names in the first column, then a set of columns with colour names assigned to each person:

queryAlldatatable

On the search page a straight forward drop down list of all the colours (using data validation from the datatable range!)

GAS – Google Sheets – Query the whole table ? No you can’t !

You would think that this should be straight-forward, but it is not.

A table full of data, with many columns, and everything to the right of Column C will have come from a list of items, but this will be different for each row, and i do not know how many columns there may eventually be. Continue reading

Google Sheets – replace filter with vlookup for array formula

Cor blimey, this one was a toughy to get to the bottom of! No amount of googling brought me the solution I needed, however by combining resources from three/four places I finally got there.

Now the filter function in Google Sheets is a lovely thing, but it doesn’t play nicely if you want an array formula, that is a formula that automagically fills down as you add more data to a sheet. So you have to convert over to using vlookup (or other method) to get the result you want. Now on the face of it vlookup will only handle one criteria, but it can be forced, with a fair bit of jiggery pokery to handle multiple criteria, and then work as an array formula.

Here was the problem. Continue reading

GAS – Sheets – Clean and Clear Layout

Sometimes, we like our spreadsheet to give focus to what is on it. General formatting: colours, borders etc. do help, but even better is to remove all unneeded columns and rows, along with other distractions. For this to work, the top of the last row needs to be visible. Here is a finished example: Continue reading

GAS – Insert Checkmark to Cell and Conditional Formatting

A little timesaver. Google Sheets doesn’t have a “Special Characters” selector, so if you want to use one you have to open up a Google Doc, copy the character you want, then back to Sheets to use it. This example shows a simple apps script for inserting a checkmark to a cell. We will then look at conditional formatting of the cell/cells. Continue reading
