Not sure if this is helpful to anyone but me, but I thought I'd share in case you weren't aware and are interested.
I have a Google spreadsheet organized by shirt/tie/suit/sport coat/etc. In those sheets, I have title, measurements, material, country, notes. I always write up the eBay title when I do measurements since the item is in front of me and I can get the most out of my keywords. I still manage to have half of my listings where the title is either 10 characters too short or 10 too long when I actually go in and list them. I figured out a way to know how many characters long my title is.
Here's a screen grab of some ties.
The number in Row G is the character count and it correlates to Row B.
The way you do it:
1. Click in an empty box that you want to correlate to the title box. (for the screen grab, it's G,510)
2. type: =len(column number and row number together with no spaces) - for the screengrab above, I typed: =len(B510)
3. hit enter. that will populate the character count. knowing eBay's limit is 80, you can then figure out where you're at and either add or delete and not have to worry about that when you go to list.
4. you can then click the box and then drag the little blue square at the bottom down as many rows as you want and it will auto-populate the corresponding row. (B511, B512, B513, et al)
Again, this may be common knowledge or not useful at all but it's been awesome for me. Thought it might help a couple people.
do you import this somehow into GarageSale? I keep thinking I'm going to have time to figure that out, but so far, nothing.
I also have a measurement spread sheet, but I print them out and write them by hand.
