Tips for table conversion
Confirm header rows and delimiter before converting.
Watch character encoding (UTF-8) for non-ASCII data.
Check that numeric IDs are not turned into scientific notation.
Validate row counts after conversion.
Keep a sample of the source until the target looks right.
Move tables between CSV, JSON, and markdown
Processing stays in your browser — your input is not uploaded to our servers.
Paste a grid and switch the serialization so you can drop it into a ticket, a fixture, or a doc. Headers and quoting matter more than people expect.
Messy Excel exports (merged cells, extra header rows) will still need a human pass.
Convert a table
Paste the source table
Include the header row if you want keys in JSON.
Pick the output format
CSV for spreadsheets, JSON for APIs, markdown for docs.
Copy and sanity-check types
Leading zeros in ids often die in CSV unless quoted.
