Download the plugin and install it
After you have installed the Excel plug in and entered your API key, you can begin writing your message.
Note: If your account is in promotional route, the messages will be sent with a random 6 digit Sender IDs assigned by the operator. To get a Sender ID of your choice, upgrade to transactional route. (Know the differences between Promotional and Transactional messages here)
After upgrading to Transactional route, you can request for a 6 alpha character Sender ID of your choice. Upon approval, you can select the Sender Names under the drop down 'Sender Name' when you next open your Excel file.
You can use existing data from the Excel sheet to form the message content and contacts. Alternatively, you can manually type the message content and contact numbers in the plugin window.
The first time you use Excel to SMS, you need to connect Excel to Fastsms India account using an API key.
You can find the API key here:
Your API key will be an alphanumeric string in the format
When you first install the plug in, you will be prompted to add your API key in to the Fastsms India window in Excel.
Click Enter to connect Excel to your Fastsms India account.
When you hit Send you will see a summary of your message.
This window will show you the content of your message and the Number of Messages you are sending (this is the number of contacts you are sending to, NOT the number of 160-character SMS credits you are using). You can also review the Date and Time scheduled for your send.
The Calculate Cost function shows you the number of SMS credits that your send will consume (1 credit = 160 characters). If your account is in Promotional route, our DND filter will automatically remove the numbers activated for DND and this will be reflected in the cost.
To send your message, click Confirm.
If you want to close the Fastsms India panel in Excel, simply click on Close button in the top right corner of your spreadsheet.
Click on the top of the plugin window and drag it to move it to a different position. You can double-click on the plugin window to expand the Excel to SMS panel again.
