Moving to a new smartphone or changing the operating system often involves the need to transfer a huge amount of data, among which contacts take priority. Users often store phone books in spreadsheets Microsoft Excel for ease of sorting and editing, but standard Android tools cannot directly read file formats .xls or .xlsx. This creates the illusion of complexity of the process, although in fact the procedure takes only a few minutes with the right approach.
The main task is to convert data into a universal format that is recognized by the operating system Android. We will consider all current methods: from cloud synchronization via Google Account to local transfer via a memory card. It is important to understand that the choice of method depends on the size of your database and the availability of a stable Internet connection.
In this article we will analyze each stage in detail, including the nuances of encoding and file structure, violation of which can lead to the appearance of “crazy words” instead of names or a complete failure of the system to import records. You will learn how to properly prepare a table so that names, numbers and additional fields are correctly distributed across the fields of your device's phone book.
Preparing an Excel file for conversion
The first and most critical stage is the correct preparation of the source document. The Android operating system and Google Contacts services do not work directly with native Microsoft Office formats. You need to bring the data into a form that is understandable for most importers - text with delimiters.
Open your file in the app Excel or a free analogue LibreOffice Calc. Make sure that the data is structured correctly: the first row should contain column headings, such as “First Name”, “Last Name”, “Phone”, “Email”. Do not use merged cells or complex formulas - only “clean” data should remain in the final file.
After checking the structure, you must save the file in the desired format. In the menu, select “Save As” and in the drop-down list of file types, find the option CSV (comma delimited). It is this format (.csv) that is the de facto standard for exchanging contact data between different platforms.
⚠️ Attention: When saving to CSV, a warning about loss of formatting may appear. This is normal because the text format does not support colors, fonts, or cell borders. The main thing is saving the data itself.
If there are commas in names or addresses, they can confuse the file structure when saving to CSV. In this case, it is better to use UTF-8 encoding and check the file in Notepad before importing.
Import via Google Contacts service (Web version)
The most reliable and recommended method of transfer is using a cloud service Google Contacts. This method ensures that your data will not only appear on your current device, but will also be automatically synchronized with all other gadgets linked to your account.
Go to the site contacts.google.com from your computer and log in using the same Google account that is used on your smartphone. In the left menu, find the “Import” button (up arrow icon). The system will prompt you to select a file - indicate the previously saved .csv document.
After downloading the file, the service will offer to compare the fields. If the headings in your Excel file are standard, Google will automatically determine which is the name and which is the phone number. However, if non-standard column names were used, you will have to manually specify the correspondence through the drop-down lists in the interface.
- 📂 The file is uploaded to the server, not to the phone, which saves the internal memory of the device.
- 🔄 Synchronization occurs automatically: changes will be reflected on the phone within a few minutes.
- 🛡️ Google creates a backup copy before importing, allowing you to roll back changes in case of an error.
After confirming the import, wait a few seconds for the process to complete. The transaction status will be displayed in a notification in the lower right corner of the screen. Now just go to the phone settings, section Accounts → Google, and press the synchronization button for new contacts to appear in the phone book.
Local import through the Contacts application
If you do not have access to a computer or Internet connection unstable, you can import directly on the device. To do this, the file .csv must first be copied to the smartphone's memory or to a microSD memory card.
Open the standard application Contact on your Android smartphone. The interface may differ depending on the manufacturer (Samsung, Xiaomi, Pixel), but the logic of actions is the same. Click on the menu (three dots or three stripes) and select “Manage contacts” or “Import/export contacts.”
Select the file source. The system will offer options: SIM card, internal storage or Google Drive. Provide the path to your CSV file. Next, the system will ask where to save the contacts: to the phone memory, to SIM or to a Google account. It is recommended to select a Google account for data security.
☑️ Check before local import
⚠️ Attention: When importing from local media, some specific fields (for example, birthdays or addresses) may not be recognized if the file encoding differs from the system one.
Solving problems with encoding and duplicates
One of the most common problems when transferring data from Excel is encoding violation. Instead of Cyrillic names, you may see a set of strange characters. This happens because Excel by default saves CSV in ANSI or Windows-1251 encoding, while Android expects UTF-8.
To fix this, open your CSV file in Notepad on your computer. From the menu, select File → Save As. At the bottom of the window, find the “Encoding” field and change it to UTF-8. Save the file, overwriting the old one, and try importing it again.
Another common problem is the appearance of duplicates. If you import contacts into a phone book that already contains some of these numbers, the system may create new entries instead of merging them. The Google Contacts service has a built-in Merge and Fix tool that automatically finds and merges duplicates.
| Problem | Cause | Solution |
|---|---|---|
| Hieroglyphs instead of names | Incorrect encoding file | Resave CSV in UTF-8 |
| Numbers are not imported | Numbers without country code | Add +7 or country code in Excel |
| Duplicate records | Re-import | Use the “Merge” function |
| Format error | Extra spaces in cells | Clear data using the TRIM function |
How to remove extra spaces in Excel?
Use the formula =SPACES(A1), where A1 is the cell with the name. Copy the formula to the entire column, then replace the original data with the resulting values using Paste Special.
Import through third-party applications
For users who often have to work with tables, there are specialized applications in Google Play Market. Utilities like SA Contacts or Import & Export provide advanced functionality for manipulating the phone book.
Such applications allow you not only to import data, but also preview it, edit it directly in the app interface and select which columns need to be transferred. This is especially convenient if your Excel file contains a lot of unnecessary information that is not needed for the phone book.
The installation process is simple: download the application, give it access to contacts and storage, select the file and click the import button. Most of these apps are free for basic functionality, but may require payment for batch processing of thousands of contacts.
⚠️ Warning: By giving third-party applications access to your contacts, you are trusting them with sensitive information. Use only proven utilities with a high rating and a large number of downloads.
Transferring contacts via a SIM card
Although this method is considered outdated due to limitations in memory capacity and number length, it is still relevant for simple push-button phones or in the absence of the Internet. The SIM card acts as a physical storage medium.
First, you need to export contacts from Excel into a format that can be easily stored on a SIM. This is usually done through middleware on a computer or specialized card readers. Then the card is inserted into the phone, and through the menu Contacts → Import from SIM card data is transferred to the device memory.
The main disadvantage of the method is the limitation on the length of the name (often up to 10-15 characters) and the lack of support for additional fields such as email, address or profile photo. All data that does not fit into the standard SIM fields will be irretrievably lost.
Using a SIM card to transfer large contact databases from Excel is not recommended due to the high risk of data loss and storage format limitations.
If you still decide to use this method, make sure that in the Excel file names are shortened to an acceptable length, and phone numbers do not contain unnecessary characters, such as brackets or dashes, that the SIM card may not recognize correctly.
Frequently asked questions (FAQ)
Can I import contacts directly from a .xlsx file?
No, standard Android tools and Google services do not support the .xlsx format directly. The file must first be converted to .csv format (delimited text).
What should you do if, after import, the numbers are displayed without a country code?
This is a common problem. Before importing into Excel, add the country code to the numbers (for example, +7 for Russia) in a separate column or using a concatenation formula to Ensure the international format.
How many contacts can be imported at one time?
There are no technical strict restrictions, but when importing more than 2000-3000 contacts at a time, the process may take a long time or cause temporary instability. Contacts application. It is better to break large databases into parts.
Where are imported contacts stored: on the phone or in the cloud?
This depends on the save location you choose when importing. If you chose a Google account, your contacts will be in the cloud. If “Phone memory” is only on the device. It is recommended to select a Google account.
How can I cancel the import if I have uploaded the wrong file?
The web version of Google Contacts has a “Undo Changes” function in the settings that allows you to roll back the state of the phone book to the time before import. On the phone itself, you will have to delete contacts manually or reset the application settings.
