4 Simple Steps to Import Excel to MongoDB Database
Connect MongoDB
Configure your MongoDB connection details (URI/host:port, authentication) — — supports standalone, replica set, sharded cluster, MongoDB Atlas, and self-hosted servers.
Select Excel File & Sheets
Select your Excel file (.xlsx/.xls) and select target sheets to import. Support partial import (specific rows/columns) and multiple sheet selection.
Configure Import Rules Mapping
Set field mapping (Excel columns ↔ MongoDB fields), data type conversion rules, data load type (append/replace/update/upsert), and empty value processing.
Start Excel Import & View Real-Time Progress
Real-time display of import speed, success/failure count, and error details. Failed rows are marked for easy retry — even for large Excel datasets.
3 Flexible Excel to MongoDB Import Types
Single Sheet to Single Collection
Import one Excel sheet to one MongoDB collection — ideal for targeted data migration or single dataset import. Preserves all columns and rows from the sheet.
Example:
Excel Sheet: employees_2024 → MongoDB Collection: employees
✅ Auto-map Excel column names to MongoDB field names (case-insensitive)
Multiple Sheets to Multiple Collections
Import multiple Excel sheets to corresponding MongoDB collections in one operation — perfect for bulk data migration from multi-sheet Excel files.
Example:
Sheets: customers, products → Collections: customers, products
✅ Custom collection naming for each Excel sheet
Multiple Sheets to Single Collection
Combine data from multiple Excel sheets into a single MongoDB collection — ideal for merging related datasets into one collection.
Example:
Sheets: sales_jan, sales_feb → Collection: sales_2024
✅ Add sheet identifier field to distinguish data sources

Frequently Asked Questions About Excel to MongoDB Import
Q: Does it support custom Excel delimiters like semicolon or pipe?
A: Yes! The importer fully supports custom delimiters including comma, semicolon, pipe, tab, and space. It can auto-detect the delimiter or you can manually configure it for precise parsing of any Excel format.
Can I import data from password-protected Excel files?
Yes! The tool supports importing from password-protected .xlsx/.xls files — simply enter the password during the file selection step. All processing remains local on your machine.
How to handle Excel column names different from MongoDB fields?
Use the field mapping feature to manually map Excel columns to MongoDB fields (e.g., "employee_name" → "name", "employee_salary" → "salary"). You can also set default values for missing fields or ignore unnecessary columns.
Does it support Excel formulas and merged cells?
Yes — formulas are imported as their calculated values (not the formula itself), and merged cells are imported as a single value in the first column of the merged range. You can configure merged cell handling rules in the import settings.
What happens if there are duplicate records in Excel?
You can choose from three duplicate handling strategies: skip duplicate records, overwrite existing records in MongoDB, or update existing records with new values. Set a unique identifier field (e.g., email, ID) to detect duplicates.
Can I import large Excel files (10GB+) without performance issues?
Absolutely! The tool uses stream processing to read Excel files in chunks, avoiding memory overflow. Large datasets are imported in batches, with real-time progress tracking and automatic retry for failed rows.
How are Excel data types converted to MongoDB types?
The tool automatically converts common Excel types: Text → String, Numeric → Int32/Int64/Double (auto-detected), Date/Time → ISODate, Boolean → Boolean. You can override these conversions in the field mapping settings (e.g., force numeric to String).
Can I schedule automated Excel to MongoDB imports?
Yes! Save your import configuration as a .bat (Windows) or .sh (Linux/macOS) file, and schedule it using Windows Task Scheduler or Linux Crontab. Perfect for daily/weekly bulk data imports from Excel.
