Everything landed in one Excel cell. Three possible reasons.
There are three separate reasons Excel does this, and they have different fixes. Here is how to tell which one you hit.

How to use Fix: Everything In One Cell
Work out which cause you hit
If you see vertical bars and a row of dashes, it came from a chat answer. If you see commas, it is a delimiter or regional-settings problem. If you see semicolons, your Excel is set to a comma-decimal locale.
Paste it in below
The converter reads all three shapes. The dashes under a header are recognised as a divider, commas and semicolons are detected, and the formatting marks around bold text are removed.
Take a real table back
Download a genuine .xlsx file, which sidesteps delimiter and encoding settings altogether, or copy it and paste again into the sheet you already have open.
Why use Parsefy Fix: Everything In One Cell?
Cause 1 — the table is markdown, not a table
Excel splits a paste into columns only when the values are separated by tab characters. A chat answer separates them with vertical bars and marks the header with a row of dashes, so Excel sees one long string per line and puts each one in a single cell. The asterisks around bold words survive for the same reason: they are ordinary characters that only the chat window renders invisibly.
Cause 2 — the delimiter does not match
Opening a .csv by double-clicking gives Excel no chance to ask what separates the fields; it uses whatever your system says and gives up if that is wrong, leaving every row in column A. Data > From Text/CSV opens the same file through the import dialog, where the delimiter can be set explicitly and previewed before anything lands in the sheet.
Cause 3 — your regional settings disagree
In locales that write decimals with a comma — much of Europe, and Indonesia — Excel expects semicolons between fields, because the comma is already spoken for. A comma-separated file then opens as one column on your machine while working perfectly on a colleague's. The setting is Windows' list separator, not something inside the file, which is why the same file behaves differently in different places.
Your data never leaves your device
Everything runs in your browser tab — there is no upload step and no server to store anything. That makes it safe for API responses, database dumps and production data you could not paste into a hosted converter.
Fix: Everything In One Cell — frequently asked questions
Why does a ChatGPT table paste into one cell in Excel?
Because the table is plain text, not a real table. Excel splits a paste into columns only when values are separated by tabs, and chat answers separate them with vertical bars. Each row therefore arrives as one string and fills a single cell.
Why does my CSV open in one column?
Because Excel is using a different field separator from the one in the file. Double-clicking a .csv gives Excel no chance to ask, so it falls back to your system's list separator. Use Data > From Text/CSV instead, which lets you choose the delimiter and preview the result first.
Why does it work on a colleague's computer but not mine?
Almost always regional settings. Where the decimal separator is a comma, Excel expects semicolons between fields instead. The file is identical; the two machines simply disagree about what separates a field, which is why the same CSV can open perfectly for one person and land in one column for another.
Can I fix a bad paste with Text to Columns?
Yes, if the rows landed cleanly. Choose the right separator, then delete the divider row of dashes and strip the leftover asterisks around bold text yourself. Converting first does those three steps for you and keeps the header row intact.
Is anything I paste uploaded?
No. Everything runs in your browser tab, so the text never crosses the network. That matters because the tables people need to fix are usually work data rather than examples.
