Execute Bulk AI Calling Campaigns from Microsoft Excel
No API setup required. Simply upload your Excel spreadsheet and let Vistara AI call every phone number, logging call duration and lead sentiment.
Updated
Direct Excel File Parsing
Upload .xlsx or .xls files directly into your dashboard.
Pre-Flight Validation
Invalid numbers, duplicates and blank rows are flagged before dialling starts rather than surfacing as failures in your results.
Any Column Becomes a Variable
Personalise the script with the model enquired about, the amount due or the appointment date from each row.
Results Export With Original Columns
Disposition, extracted fields and transcript links appended to your data, ready to merge back.
Excel remains the most widely used business tool in India, and for calling campaigns that is entirely reasonable. A spreadsheet is portable, requires no permissions, and is understood by everyone in the office. Requiring an API integration before the first call is the most reliable way to ensure a pilot never happens.
Upload the file, map the columns, choose an agent, and the campaign runs. Results come back as a file with your original columns intact plus the call outcomes beside them, which drops straight back into whatever process you were already running.
Preparing a File That Produces Clean Results
Most disappointing first campaigns trace to the file rather than the agent. These six checks take ten minutes and prevent a week of confusing metrics.
- One phone column, one format — Mixed formats with and without country codes are the leading cause of failed dials. Decide and apply consistently.
- Deduplicate first — The same person on three rows gets three calls, which reaches the customer before it reaches your report.
- Include personalisation columns — An agent that opens with the specific enquiry performs noticeably better than one that opens generically.
- Add a source column — So you can compare performance by lead source afterwards. It cannot be added retrospectively.
- Remove opted-out contacts — Check against your suppression list before uploading, not after the calls have gone out.
- Test on twenty rows first — Including your own number. A mapping error caught on twenty rows costs nothing.
Knowing When to Stop Using Files
File upload is the right starting point and the wrong long-term answer for anything recurring. These are the signals to move on.
- Uploading more than weekly — Manual repetition is where forgotten uploads and format errors enter the process.
- Speed to lead matters — A daily upload cannot deliver a 30-second callback. If timing is your value, you need a webhook.
- Results need to reach the CRM — Manually merging outcomes back is tedious and reliably stops happening after a few weeks.
- Several people run campaigns — Shared manual processes drift, and different people prepare files differently.
- Volume is growing — Past a few thousand contacts a month the manual overhead clearly outweighs the integration effort.
The right sequence is file upload for the pilot, integration once the calls are proven. Teams that build the integration first frequently spend three weeks on plumbing before discovering the script needed rewriting.
