Clean CSV data without all the manual work.

Duplicate-free CSV files shouldn't mean hours of formulas, filters, vibe-coding, or checking rows one by one.

Manually cleaning old exports, legacy databases, lists form different systems, or data before your time takes time, leaves more room for mistakes, and often means figuring out processes someone else set up years ago.

Upload all your CSV files to Dedupely, find and merge every duplicate and export clean data, ready for whatever comes next.

CRM not needed.

Not every data set lives in a CRM. Dedupely works directly with CSV files, so a CRM connection isn't required. Upload as many files as you need, keep each dataset completely separate, and export the clean version when you're done.

PS. You can upload multiple CSV files and connect different CRM instances at the same time, in the same account, without any of them mixing together.

Duplicates in CSV?
It's a very solvable problem!

Are you merging records from a file?

We built a two-way, simultaneous integration on multiple CRM's and Excel/CSV. No need to download or upload anything from or to your CRM.

Why does Dedupely need to sync my data?

To apply our match and merge engine our algorithm needs access to your records. Once the sync is ready you will be able to match and merge your duplicates.

Can I choose which records to sync?

The first sync we will sync all of your records to make sure we get all objects, fields and columns. We will always sync all the records in a particular record type.

FAQs

How does Dedupely find duplicates?

Dedupely uses match options that you define to detect duplicates. You can compare fields like name, email, phone number, company name, or custom fields, using exact or similar matching. Once set, Dedupely scans your CRM and groups duplicates into match sets for you to review before merging. You have full control over the criteria used to detect duplicates, ensuring that only the right records are flagged for merging.

Explore all the ways to find duplicates

Can I control which duplicates get merged?

Yes! With Dedupely, you decide which records are considered duplicates by setting match options and merge rules. Match options define what counts as a duplicate, while merge rules control how individual fields are merged. Dedupely follows your CRM’s native merge structure, which means merging happens on a field-by-field basis: not by selecting a single “winning” record. You have full control over the logic, ensuring your most important data is kept.

Check out how merge rules work

Does Dedupely work automatically?

Yes! You can create a search pad with your preferences and match options, to run and merge automatically, based on a schedule of your choice.

How do I make sure the right data is kept when merging?

Dedupely gives you full control over what data is kept by letting you define merge rules for each field. You can choose to keep the most recently updated value, prioritize data over blanks, or apply custom logic, like selecting a specific owner or the highest score. Since merging happens field by field, you can preview results before confirming, and winning values are highlighted so you know exactly what will be kept.

Customize how your duplicates merge

Can I review merges before they happen?

Yes! You can manually review every merge before confirming, or use auto merge with pre-set safety rules to streamline the process.

Here’s what happens when you merge

Does Dedupely replace my CRM’s built-in duplicate management?

No. Dedupely enhances your CRM’s duplicate management with more flexibility, automation, and advanced matching options.

Setting up Dedupely with your CRM
