General Efficient Read In of Static Data

[thegoat001]

Hi All,

I have a large amount of static data i.e. it will never need to be changed.

It's 146,000 rows by 20 columns.

What I typically do is use a macro to read data in from a sheet cell by cell and then store it into an array. Saving the data this way seems to be pretty time consuming. Turning off the screen refresh does help though.

From an efficiency perspective, would it be better to actually include the data directly in the VBA code instead of referencing a sheet?

Thanks in advance.

Probably, time it and see

You can read a range into VBA without looping through each cell:

Dim vInput As Variant

vInput = Range("A1:T146000").Value2

But whether it is better to process an Excel range or a VBA array depends on what you intend doing with the data?

In some cases, it may be easier and more efficient to use Excel native functions rather than writing code to loop through a VBA array.
