If you experience a situation where you've exported records from SigParser and the CRM Contact or Account IDs don't match this article will help you.
Salesforce's API exposes all the IDs with 18 characters but the Export from the Salesforce app generates IDs that are only 15 characters.
How to resolve this
You can create a Formula field on the Contact or Account using the function CASESAFEID(id) to convert the 15 character ID into an 18 character ID that can be compared to the value coming out of SigParser's export.
In Salesforce Setup section:
Go to your Object
New Field. Name is "Full ID" or whatever you wish
Type = Formula
Output = Text
Type CASESAFEID(Id) as the entire formula. Save.
Go to your Report and use your new field!
