excel truncated leading zeroes on some fields, and saved some other fields in scientific notation without me realizing.  'i.e. +1.24e4'.  I used excel to manipulate my data from salesforce before importing into zoho.  I've been putting live data into zoho that i don't want to lose, that i'm pretty sure i would if i did the undo.

The issue if zoho retained the original record id's i could easily match on it, but it didn't.  I could try to export everything from zoho to get the zoho record id's, then try and do some matching on multiple fields, but i'm concerned that i may not get correct matches since i've changed enough data between salesforce and zoho...  

so before i just hit the undo button on the imports, any options I'm missing?
