Enrich a sheet without leaving the browser

Each empty cell becomes an Answers API call using the rest of the row as context — the same pattern you would run in a backend job.

Row context
Filled cells become the prompt context for empty fields on that row.
Your columns
Rename headers to the fields you want: industry, HQ, CEO, and so on.
CSV in and out
Paste or import a small sheet, then export the enriched result.

How it works

Each tool is designed around a direct job: provide the input, get a useful output, and move it into your workflow.

1
Add names or facts
Fill the first column and any context you already have.
2
Run enrichment
Empty cells are filled via /v1/answers, one field at a time.
3
Export the sheet
Copy or download the table for the next step in your workflow.

Built for practical workflows

These tools are small on purpose: they solve the conversion job quickly, then point teams toward the API path when the workflow becomes recurring or high volume.

Lead lists
Append industry or description to a short company list.
Fundraise research
Fill HQ, employees, or category on a target list.
Ops cleanup
Complete missing fields before a CRM import.

Need this at scale?

Call POST /v1/answers per row with a task plus a json schema for the missing fields. The snippet on this page is that payload.

Frequently asked questions

Product & Capabilities

How many rows can I enrich?
This playground caps at 15 rows so the run stays inside the page timeout.
Do I need an API key?
Signed-in users can run on the site key or their own Olostep key, depending on the page auth state.
What columns can I add?
Any field name. The Answers task asks for that field using the rest of the row as context.

Usage & Automation

Which API does it use?
POST /v1/answers once per empty cell, with a json schema for that field.
Can I automate this?
Yes. Loop rows in your backend with the same Answers payload.
Does it write back to Google Sheets?
Not in this playground. Export CSV and import where you work.

Pricing & Plans

Is this tool free to try?
The page UI is free to use. Live runs use the Olostep API configured for this site and may be rate limited.
How is API usage priced?
Olostep is usage based. See pricing for current plan details and included credits.
Do I need a credit card to start?
New Olostep accounts include free credits so you can test extraction before scaling.
