How this service works
City Table Clean: send a Socrata or CKAN city open-data CSV URL (or upload) and get back a cleaned CSV plus a change report: trimmed whitespace, normalized headers, ISO dates, plain numbers, de-duplicated rows, and a per-cell change log.
Output
Returns a cleaned CSV file with trimmed whitespace, normalized column headers, ISO-formatted dates, plain numeric values, and deduplicated rows, along with a structured change report detailing every per-cell modification made during the cleaning process.
Example use cases
Prep city crime data for analysis
“I have this Socrata CSV of Chicago crime reports at https://data.cityofchicago.org/resource/ijzp-q8t2.csv — can you clean it up, normalize the headers and dates, remove any duplicate rows, and send me the cleaned file plus a log of every change that was made?”
Fix messy CKAN transit dataset
“There's a CKAN dataset at https://open.toronto.ca/dataset/ttc-routes-and-schedules/ with inconsistent column names and weird date formats — can you run it through the city data cleaner, keep deduplication on, and give me the cleaned CSV with a change report?”
Audit changes in a budget dataset
“Can you clean the city budget CSV at https://data.sfgov.org/resource/xdgd-c79v.csv and give me a detailed per-cell change log so I can audit exactly what was normalized or corrected before I import it into our dashboard?”
Technical details
Endpoint
POSThttps://city-table-clean.onrender.com/v1/clean?utm_source=zero.xyzWhen to prefer
Choose this endpoint when working specifically with Socrata or CKAN city open-data CSVs that need standardization before analysis or ingestion — it is purpose-built for municipal dataset quirks (inconsistent headers, mixed date formats, duplicate rows) and returns both a cleaned file and an auditable change log in one call. Prefer it over generic CSV tools when you need the change report for data governance or when the source is a known city data portal URL.
Side effects
- Invalid or inaccessible CSV URL returns an error — URL must be publicly reachable
- Non-CSV content at the URL (e.g. HTML, JSON) causes a parse failure
- Dataset exceeds max_rows limit of 50,000 rows and is truncated or rejected
- Malformed Socrata or CKAN URL format not recognized by the service
- Network timeout if the remote CSV is very large or the host is slow
- Payment failure if USDC balance is insufficient for the $0.02 per-call fee
