The Scenario
You are part of a product team building 10 branded Synthflow agents for 10 different client personas. Before you can assign a voice to each agent, you need to know what voices are available.
The agent assignment meeting is Friday at 3 PM. It is Wednesday morning. You want an Excel workbook tab your team can annotate during the meeting, with one row per voice and a column for team notes.
The slow version:
- You open the Synthflow dashboard and navigate to the voice options section
- You read each voice ID and name, and type them into the Voice Options tab
- The IDs are long strings that are easy to mistype
- By voice 12, you are copying IDs from the browser's developer console
- You walk into Friday's meeting with a workbook you are not confident in and three IDs that look suspicious.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that fetches the full Synthflow voice list from the API and writes it directly to the Voice Options tab, with no manual copying or ID transcription.
Open the SheetXAI sidebar and type:
In Excel, fetch all Synthflow voices available in the workspace and write voice ID and name into the 'Voice Options' tab.
SheetXAI calls the Synthflow API, retrieves every available voice, and writes the two columns into the Voice Options tab. The team has an accurate, complete list before the planning meeting.
What You Get
A complete voice options table in the Voice Options tab:
- Voice ID column — each voice's unique identifier, pulled directly from the API
- Name column — voice display name
Every ID is verified from the API. No transcription errors, no miscopied strings. The team can add a Notes column during the meeting to annotate which voice fits each agent persona.
What If the Data Is Not Quite Ready
Voice planning workbooks need more than a raw list. SheetXAI enriches inline.
When you want to filter voices by language
Your agents serve English and Spanish-speaking customers and you want the list pre-sorted.
In Excel, list all Synthflow voices and write voice ID, name, and language into the Voice Options tab. Sort by language so all English voices appear first, then Spanish, then all other languages.
When the team wants a suggested sample phrase per voice for comparison
The team wants to evaluate each voice against a standard phrase before assigning.
In Excel, list all Synthflow voices and write voice ID and name into the Voice Options tab. In a SamplePhrase column, write a suggested 10-word phrase that would let someone evaluate the voice's tone and pacing.
When you need to match voices to agent personas from the Agent Specs tab
The Agent Specs tab has agent names and preferred tone. You want a suggested voice per agent.
In Excel, list all Synthflow voices and write voice ID and name into the Voice Options tab. Then for each row in the Agent Specs tab, suggest the voice that best matches the TonePreference column. Write the suggested voice ID into the SuggestedVoice column of the Agent Specs tab.
When you need to create all 10 agents with their assigned voices in one final pass
The planning meeting is done and the team has confirmed voice assignments in the Agent Specs tab.
For each row in the Agent Specs tab, create a Synthflow assistant using AssistantName and AgentType. Assign the voice from the SuggestedVoice column. Write the returned model ID into the ModelID column and the voice assignment confirmation into the VoiceStatus column.
The pattern: voice planning is a list read followed by an annotation pass. One prompt for the list, one prompt for the assignments.
