# CSV Enrichment: What is the right format for the CSV file enrichment?


## New Feature: CSV Enrichment Just Got Smarter at LeadDelta

We’re excited to introduce one of our most powerful updates yet — **CSV Enrichment via LinkedIn Profile URLs**. With just a simple list of LinkedIn URLs, you can now uncover your prospects’ **personal email**, **business email**, and even their **phone number** — directly inside your LeadDelta workspace.

Whether you're enriching 50 or 15,000 contacts, all it takes is one key identifier:  
➡️ `https://www.linkedin.com/in/username`

Yes, that’s it. No names, no company domains, no emails needed upfront. Just paste in LinkedIn profile URLs, and we’ll do the rest.

### 🧠 Why It Matters

* **Save time** — Skip the manual work of filling in names or guessing email patterns.   
* **Maximize success** — Only verified, high-quality contact data is returned.   
* **Boost targeting** — Instantly export enriched data into your sales or marketing workflows.    
* **No guesswork** — LeadDelta only charges credits for successful finds. 

### 🗂 File Upload Guidelines

To get started, you’ll need to upload a CSV file that meets the following requirements:

**✔️ File Format:** `.csv`  
**✔️ File Size Limit:** Up to 5MB  
**✔️ Max Rows:** 15,000 LinkedIn URLs per file  
**✔️ Encoding:** UTF-8 (for special character compatibility)  
**✔️ One Sheet Only:** Multi-sheet files won’t work  
**✔️ Header Row Required:** Include a descriptive column name like `LinkedIn URL`

👉 [Download our sample CSV file](https://docs.google.com/spreadsheets/d/1ueKFo7RiKVdnNuhYCJG4SUvriXA_thNZ0GLOGmlO1mA/edit?usp=sharing) and use it as a starting point.

> 💡 Pro tip: We recommend using **Google Sheets** instead of Excel to avoid encoding or formatting issues. Once done, simply download your sheet as a CSV and upload it to LeadDelta.


### ⚠️ Troubleshooting Uploads

If your file:
* isn't in `.csv` format    
* is too large    
* lacks a LinkedIn URL column    
* or includes unsupported encoding
...you’ll see an error message. No worries — just double-check your file using the guide above.

### 🚀 Ready to Enrich?

Once your file is uploaded, we’ll start enriching each profile. You’ll see real-time progress, and when it’s complete, you can **export your enriched data** with just a click — ready to be used in CRMs, campaigns, or outreach tools.
