I will turn your API or json data into a tested CSV automation
Richard A.
About this gig
Need usable data instead of a raw API response? I will turn your documented API or supplied JSON structure into a tested command-line export for CSV or clean JSON.
You receive the reusable Node.js or Bash source, configuration placeholders, sample output, run instructions, and a clear verification step. Standard covers one documented endpoint. Premium can cover pagination or up to three closely related endpoints in one export workflow.
Real credentials never belong in the delivered source. You can provide redacted sample data and insert your own token through an environment variable when you run the tool.
This Gig covers data retrieval and transformation. It does not include scraping a site that forbids it, bypassing access controls, reverse engineering a private API, buying API access, a hosted dashboard, or an unrelated application backend.

FAQ
Do I need to give you my production API token?
No. I can build and test against redacted samples, public documentation, or a safe test environment. The delivered tool reads your token from an environment variable when required.
Can you handle pagination?
Yes. Choose Premium when pagination is central to the export. Standard fits one documented endpoint with a bounded response.
Can the tool create Excel files?
The listed packages deliver CSV or JSON. CSV opens directly in Excel and avoids adding a fragile spreadsheet dependency. Native XLSX output can be agreed separately before ordering.
Which language will you use?
Usually Node.js for HTTP and structured data or Bash for a small Unix pipeline. I choose the simpler maintainable option for your target environment and state it before work begins.
Will you scrape a website without an API?
No. This Gig uses an authorized documented API or data you are allowed to provide. It does not bypass logins, bot protection, payment walls, or access controls.
What does a revision cover?
A revision corrects the agreed field mapping or behavior using the original API, input structure, and requested output. A new API or unrelated workflow is a new scope.
