Import Data Into Salesforce From Excel: Step-By-Step Import Guide

I spent a whole afternoon wrestling with CSV files before realizing Excel to Salesforce imports could be this simple. Between you and me, the Data Import Wizard is your best friend here.

You’ll need a clean spreadsheet with matching field names and no hidden characters. I’ve seen imports fail because of a single rogue space in column headers—don’t let that be you.

The process itself takes under 10 minutes once your data’s prepped. Map the fields carefully, run the import, and watch Salesforce pull everything in without breaking a sweat.

Works for contacts, accounts, or custom objects. First time I nailed this, I saved my team three hours of manual entry.

What Youll Need

Instructions

Here’s the procedure I follow to get clean data into Salesforce without errors or duplicates.

Open your spreadsheet and ensure each column header matches a Salesforce field name exactly. I always remove any special characters, leading spaces, or inconsistent capitalization from headers—even a single mismatch will cause the import to fail.

Delete any rows with incomplete data and verify that required fields (marked with an asterisk in Salesforce) are populated for every record. Use Data > Remove Duplicates in Excel to eliminate duplicate entries, which would otherwise create redundant records in Salesforce.

Save the file as a .csv format, as Salesforce’s import tool works most reliably with this type. Close the file completely before proceeding to avoid locking issues during the upload.

Navigate to Setup > Data > Data Import Wizard in Salesforce. Select the object type you’re importing to, such as Accounts, Contacts, or a custom object. Upload your prepared .csv file when prompted.

On the mapping screen, Salesforce will auto-detect headers that match standard field names. Manually verify each mapping—especially for custom fields—and correct any mismatches. Pay special attention to picklist fields, as the values in your file must exactly match the picklist options in Salesforce.

For date fields, ensure your Excel dates are formatted as MM/DD/YYYY to prevent conversion errors. The preview at the bottom of the mapping screen will show how your data will appear in Salesforce—review this carefully.

Choose whether to trigger workflow rules and processes during the import. I typically enable these to ensure automation runs as expected, but disable them if you’re troubleshooting import issues. Set the Record Owner to an active user who should own these new records.

For large datasets (over 50,000 records), select Bulk API instead of the standard API to avoid timeout errors. The bulk process is slower but more reliable for high-volume imports. Click Start Import when ready.

Salesforce will send you an email confirmation when the import completes. You can also monitor progress in Setup > Data > Monitor Bulk Data Load Jobs. Wait for the Completed status before verifying the data.

Navigate to the object tab in Salesforce and run a report to spot-check the imported records. I always verify that the record count matches my Excel file and that a sample of records contains the expected data in all fields.

Check for errors in Setup > Data > Bulk Data Load Jobs. Any failed records will appear here with error messages. Common issues include invalid picklist values, exceeding character limits, or violating validation rules.

If you find errors, correct them in your Excel file and re-import only the failed records. Use the External ID field to update existing records rather than creating duplicates. This iterative approach saves time compared to starting over.

Tips and Common Mistakes

Small oversights in data import can create big headaches, but these strategies prevent most issues.

Header Precision: In Step 1, even a single space or capitalization difference in your Excel headers will break the mapping. I use Excel’s TRIM and CLEAN functions to strip hidden characters and standardize formatting before saving as .csv. This catches issues the import wizard would otherwise miss.

Picklist Validation: During Step 2, Salesforce won’t warn you if your Excel values don’t match picklist options—it’ll just fail silently. I always export the existing picklist values from Salesforce first, then copy-paste them into my spreadsheet to ensure exact matches, including capitalization and punctuation.

Bulk API Threshold: For Step 3, the 50,000-record cutoff for switching to Bulk API isn’t arbitrary. I learned this after timing out on a 48,000-record import. Now I err on the side of caution: if I’m anywhere near that number, I use Bulk API regardless. The extra minutes are worth avoiding a failed import.

Error Handling Workflow: In Step 4, don’t assume a “Completed” status means success. I once wasted hours verifying data only to find 2,000 failed records hidden in the Bulk Data Load Jobs section. Now I check there first—it’s the only place you’ll see the actual error messages for failed rows.
