# Reuse previously logged data for faster Carbon Accounting
### **Overview**
Many categories of emissions remain consistent from year to year. To help you avoid repetitive manual entry, Cozero now offers a **data duplication feature** that lets you quickly reuse previously logged information.
This feature allows you to export past entries into a ready-to-use template, make minor adjustments, and re-import them into your workspace. The result: faster, more consistent reporting with less effort.
The feature has been released on August 27, 2025 and is available to all Cozero users.
### **Key benefits**
- **Save time** by exporting previously logged entries directly into Cozero CCF BI template
- **Target your data** by selecting the exact period, category, and subcategory you want to duplicate
- **Stay consistent** while making quick updates before uploading the file back into Cozero
### **Video Tutorial**
### **Step by step Tutorial**
### Step 1: Navigate to the Log Entry Overview
- Navigate to Corporate Footprint section under Log on the platform
- Locate the **Log Entry Overview** (three dots above emissions in the log entries view)
- Click on the **'Export to bulk template'** option from the drop down menu
### Step 2: Filter and select your data
Use the filters to define the:
- **Period** (e.g., 2024 emissions data)
- **Category** (e.g., purchased goods and services, electricity)
- **Subcategory** (e.g., raw materials)
This ensures only the relevant records are included in your export. You can define multiple categories in a single file if needed.
After selecting all the relevant option click **Export**
### Step 3: Export to template
- Clicking **Export** will generate a pre-filled **CCF BI template** containing the selected entries.
- Just like CCF bulk import template, you will receive an email containing a link to download the relevant exported logs
- Open the exported file in excel or google sheets
### Step 4: Update the template
- Open the **Data Input Sheet** in the file, where you’ll add your activity data.
- This sheet will contain the existing logs you selected in the previous step filled according to the template required for bulk import later.
- Please make sure to not change any formatting and always save the file back in original excel format .xlsx.
In case of any confusions you can use the **data guide sheet** to understand the different values that go in the various fields of the input contains instructions, examples, and a reference for required fields. Use it to find the correct match for your activity data. To understand better on how to fill the values from scratch you can refer to the following [link](https://resources.cozero.io/wiki/bulk-import-for-corporate-carbon-footprint?hsLang=en).
### Step 5: Upload the updated file
- Next, return to the platform and navigate to bulk import section under Log -\> Corporate footprint -\> Bulk import -\> Upload file
- Now add the file you edited in the previous step
- If the file has no issues it will pass the validation step. In case of failure please download the error files and fix the errors highlighted. For more information on how to troubleshoot and manage Bulk import please refer to the [link](https://resources.cozero.io/wiki/bulk-import-for-corporate-carbon-footprint?hsLang=en).
- Once the file passes validation and calculation is complete you will receive an email confirmation.
### 
### 
### Step 6: Validate and confirm
- Review the imported entries in the Log Entry Overview.
- In case you are unable to review the data you uploaded please contact support at support@cozero.io
