DataChecker Pro vs Dedupely
Both tools handle duplicate contacts. The difference is when in the workflow each one works — and what else they fix along the way.
DataChecker Pro
Scan your CSV for duplicates, bad emails, phone formatting issues, name casing problems, and misplaced data — all before you import into any CRM. One clean file in, one clean file out.
Dedupely
Connects directly to HubSpot and Salesforce to find and merge duplicate records that already exist in your CRM. Focused specifically on deduplication — doesn't handle other data quality issues.
The key distinction: before vs. after
Duplicates in your CRM are almost always caused by duplicates in the data that went into your CRM. Cleaning before import is cheaper, faster, and prevents the problem from occurring. Cleaning after is expensive — merging live records risks data loss, association confusion, and audit headaches. One Reddit HubSpot user described it well: "LinkedIn integrations usually break at the contact creation level. When every new connection instantly becomes a record without validation, HubSpot CRM fills up with duplicates fast."

Who should use each tool
DataChecker Pro is better if you:
- ✓ Are preparing a CSV for an initial HubSpot import and want to catch duplicates before they enter
- ✓ Need to fix more than just duplicates — bad phone formats, email typos, casing issues
- ✓ Work with client data and don't have (or want to give out) CRM credentials
- ✓ Are doing a one-time migration and don't need a monthly subscription
- ✓ Want a single tool that handles the full pre-import data quality checklist
Dedupely is better if you:
- → Already have duplicate records inside a live HubSpot or Salesforce CRM that need merging
- → Need to set up ongoing, automated deduplication rules inside your portal
- → Your data quality problem is specifically duplicates (not formatting or validation)
- → You have CRM admin access and want to clean up post-import

Frequently asked questions
Can DataChecker Pro merge duplicate records inside HubSpot?
No — DataChecker Pro works on your CSV file before import, not inside your live CRM. It flags rows in your spreadsheet that look like duplicates so you can decide which to keep before anything hits HubSpot.
If I use DataChecker Pro before importing, do I still need Dedupely?
For most initial migrations: no. If you clean your CSV thoroughly before import, very few duplicates should enter your CRM. Dedupely becomes more relevant for ongoing data quality management once your portal is live and data is continuously added from multiple sources.
Does DataChecker Pro require connecting to HubSpot?
No. You upload a CSV file, DataChecker Pro scans it and flags issues, you download a clean version. No CRM connection, no API keys, no portal access required.
What duplicate detection method does DataChecker Pro use?
DataChecker Pro flags rows as potential duplicates when two or more rows share the same name AND match on email or phone. It handles minor formatting differences (like E.164 vs local format phones) when comparing.
Can I use DataChecker Pro and Dedupely together?
Yes. Use DataChecker Pro to clean your CSV before the initial import, then Dedupely if ongoing deduplication is needed inside the live portal. They operate at different stages.
