Extract tables from pdf (to excel), pref. w/ vba
You have a number of ways to dissect a text file and depending on how complex it is might cause you to lean one way or another. I started this and it got a bit out of hand... enjoy.
Based on the sample you've provided and the additional comments, I noted the following. Some of these may work well for simple files but can get unwieldy with bigger more complex files. Furthermore, there may be slightly more efficient methods or tricks to what I have used here but this will definitely get you going an achieve the desired outcome. Hopefully this makes sense in conjunction with the code provided:
- You can use booleans to help you determine what 'section' of the text file you are in. Ie use
InStron the current line to determine you are in a Table by looking for the text 'Table' and then once you know you are in the 'Table' section of the file start looking for the 'Assets' section etc - You can use a few methods to determine the number of years (or columns) you have. The
Splitfunction along with a loop will do the job. - If your files always have constant formatting, even only in certain parts, you can take advantage of this. For example, if you know your file line will always have a dollar sign in front of the them, then you know this will define the column widths and you can use this on subsequent lines of text.
The following code will extract the Assets details from the text file, you can mod it to extract other sections. It should handle multiple rows. Hopefully I've commented it sufficient. Have a look and I'll edit if needs to help out further.
