Input / Output
Input, output, and copy actions stay in this main surface. Examples and reference checks are separated below.
Local session
Input state is saved only in this browser so you can restore the last workspace without an account.
Open examples, checks, and related tools only after the primary input/output flow is done.
Clean CSV for API use
Trim CSV rows, remove duplicates, convert to JSON, and make a quick Markdown table for review.
Trim cells, drop empty rows, detect duplicates, and convert rows to JSON.
Sort or dedupe key lists before they become API payload values.
Create a Markdown table so teammates can review the cleaned data quickly.
Review a SQL query
Format a query, copy the SQL review report, then compare or inspect result payloads before handoff.
Format the query and copy the review report with table, clause, mutation, and checklist signals.
Compare the reviewed query against the previous version before sharing it.
Clean exported result rows or API payload samples that prove the query output shape.
