Transfer existing data with Zapier using a spreadsheet

When you need to move existing records from one tool to another, Zapier can help you transfer data in bulk using a spreadsheet. This guide explains how to prepare your file, set up a Transfer, and safely move historical data into your apps.

This process is ideal for one-time or occasional imports, such as migrating contacts, updating records, or syncing legacy information from CSV or Excel files.

What you need before starting in Zapier

Before configuring any automation, make sure you have the right prerequisites in place. Proper preparation reduces import errors and avoids duplicate data in your destination app.

• An active Zapier account with access to the Transfer feature.
• A supported spreadsheet file, usually CSV or another format your chosen source app or storage supports.
• Access to the apps you want to connect as source and destination.
• Clarity on which fields must be transferred and how they should map across apps.

Prepare your spreadsheet for Zapier Transfer

A clean, well-structured spreadsheet is essential for a smooth import. Spend time organizing your data before connecting it to Zapier.

Format your columns and headers

Set up your spreadsheet so each column represents one field you plan to send to your destination app.

• Use descriptive column headers, such as First Name, Email, or Created Date.
• Keep one header row only; do not merge header cells across multiple rows.
• Place your data immediately below the header row, one record per row.
• Remove any totals, formulas, or notes below the last data row.

Clean and validate your data

Cleaning data before sending it through Zapier reduces the risk of errors during Transfer.

• Check for missing required values, like email addresses for contact imports.
• Standardize date formats and phone number formats where possible.
• Remove duplicate rows if your destination app does not allow duplicates.
• Confirm that values match any expected format, such as dropdown options or status labels used in your target app.

When your spreadsheet is ready, save it in a supported location, such as cloud storage, a CSV export, or a connected app that will act as the source for Transfer.

Start a Transfer with Zapier

Once your spreadsheet is prepared, you can configure a Transfer to bring the data into your chosen app. Transfer is different from a regular Zap because it focuses on moving existing data instead of triggering on new events.

Open the Transfer experience in Zapier

1. Sign in to your Zapier account.
2. From your dashboard or navigation, look for the Transfer option.
3. Choose to create a new Transfer, which will guide you through the setup flow.

This workflow is designed specifically for batch imports and historical data moves, not continuous real-time automation.

Select your source app or spreadsheet

The source is where Zapier will read your existing records from.

1. In the Transfer setup, choose your source app or storage location.
2. Connect or authenticate the account if you have not linked it before.
3. Browse to the file, spreadsheet, or table that contains your data.
4. Select the specific sheet, table, or view to use if the app offers multiple options.

After selecting the source, Zapier will scan the available columns or fields so you can map them to your destination.

Connect your destination app in Zapier

The destination is where each row in your spreadsheet will be turned into a new record or used to update existing records.

Choose the destination app and event

1. In the next step of Transfer, select your destination app.
2. Choose what you want to do with each row, such as create a new record or update an existing record, depending on what the app supports.
3. Connect your destination account if you have not done so earlier.

The available actions vary by app, so review your options carefully before continuing.

Map spreadsheet fields to destination fields

Field mapping tells Zapier how to translate each column in your spreadsheet into the correct field in the destination app.

1. For each destination field, choose the matching column from your spreadsheet.
2. Ensure all mandatory fields in the destination are mapped to valid source columns.
3. If needed, map optional fields such as tags, notes, or custom fields to include more detail.
4. Confirm that data types align (for example, dates to date fields, numbers to numeric fields).

Take time to review mappings. Incorrect mapping can create incomplete or inaccurate records in your destination app.

Filter and preview data in Zapier Transfer

Before running your Transfer, refine which records you want to move and preview how Zapier will send them.

Apply filters to narrow rows

If your spreadsheet contains more data than you want to import, use filters in Transfer where available.

• Filter by date ranges, such as only importing records created after a specific date.
• Filter by status or category, such as active customers only.
• Exclude rows that do not contain required fields.

Filtering helps you keep your Transfer focused and avoids loading irrelevant or outdated information.

Review the data preview

Transfer provides a preview of how each row will appear once processed.

1. Check a sample of rows in the preview screen.
2. Confirm that names, emails, dates, and other fields appear in the correct destination fields.
3. Look for obvious formatting issues or misalignments.
4. Return to the mapping step if you see anything that needs adjustment.

This preview is one of the most important safeguards before you run your Transfer live.

Run and monitor your Zapier Transfer

After confirming the preview, you are ready to process the records and move them into your destination app.

Run the Transfer

1. Click the option to start or run the Transfer.
2. Zapier will begin processing the selected rows from your spreadsheet.
3. Depending on volume, the Transfer may take some time to complete.

During this process, avoid changing the source spreadsheet structure, as that may cause unexpected behavior.

Monitor results and handle errors

When the Transfer finishes, review the outcome to ensure everything imported correctly.

• Check the summary of successfully processed records.
• Review any error messages or failed rows provided by Transfer.
• Correct issues in your source file or mapping, then rerun a new Transfer for failed rows if needed.
• Spot-check data directly inside the destination app to confirm it appears as expected.

If you need further detail on any of these steps, refer to the original help article at Transfer existing data using a spreadsheet.

Best practices for using Zapier with spreadsheets

Following best practices helps you make the most of Zapier when importing spreadsheet data.

• Always back up your destination app data before large imports.
• Test your setup with a small subset of rows before importing the full spreadsheet.
• Document your field mappings in case you need to repeat the process later.
• Use consistent naming conventions for columns to simplify future Transfers.

By combining a well-structured spreadsheet with the Transfer feature, Zapier gives you a controlled, repeatable way to migrate or update large volumes of existing data across your tools.
