Common Issues
1. JSON Highlighting is missing
The problem: You pasted API payload JSON into the editor but it renders as just blank or black-and-white text without colors.
The solution: Be sure that your editor is actually toggled from **CSV** to **JSON** in the settings. If it is already switched to JSON, then your payload is likely invalid—ensure you have matching `{}` brackets, quoted `"keys"`, and no trailing commas at the end of lists, which are common errors causing `JSON.parse` to fail.
2. CSV headers are missing
The problem: The PDF renders the CSV data as a table, but the table lacks a bolder HTML header row `<th>`.
The solution: Our table generator automatically assumes the first line of your CSV document contains your table headers. Do not begin the CSV with empty newlines or data rows. Format it like so: `id, name, age\n1, John, 20`.
