What this page cannot tell you
- This is 1,000 published rows we pulled on 25 Aug 2026, not the city's all-time file. A row we did not pull is not in the file.
- Person-name and contact columns are stripped from every file we make. The portal still has them. We will not put them in a paid file.
- A blank cell means the city left it blank. We do not fill it in.
- The City of Chicago's required notice is printed on this page and travels with the file, character for character. We do not paraphrase it.
See the file we hold
You do not have to take our word for what is in the file. Here are 25 rows of the real thing, carrying all 41 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.
- Open the 25 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
- The same 25 rows as JSONThe same rows again, laid out for reading with code.
Nothing on this page is for sale. The sample file is free to read, and so is every row on the page above it.
These 25 rows are a slice of the file, not the whole of it. What we cannot show you here is how far back it goes: the file goes back further than these rows do.
Not on sale right now
Not on sale right now. We have not yet confirmed that this city's data terms allow us to sell files made from it, and we cannot yet deliver a file automatically after payment, so we are not taking payment.
