Questions
What is CSV?
CSV is a text format for tabular data. The first row usually names the columns. Later rows are records, with commas separating fields.
How does CSV to JSON conversion work?
The tool parses the CSV in the input, uses the first row as object keys, and turns each later row into a JSON object. Conversion runs only when you press Convert to JSON.
Does the first row become the JSON keys?
Yes. The first CSV row is the header. Each following row becomes one JSON object.
Are numbers converted to JSON numbers?
No. Every CSV value stays a string, including values that look like numbers, booleans, or null.
How are quoted commas handled?
A comma inside double quotes is part of the field, not a column break. Doubled quotes inside a quoted field become a single quote character.
What happens if rows have different numbers of fields?
Conversion stops with an error such as “Row 4 has 5 fields; expected 4.” Extra values are not dropped and missing values are not invented.
Can CSV fields contain line breaks?
Yes, when the field is quoted. A quoted field may span multiple lines and still counts as one value.
Does IngoHub store my CSV?
No. Pasted CSV and local files are processed in your browser for this page session and are not stored or sent to an IngoHub account or API.
Can I upload a CSV file?
Yes. Choose a .csv file on your device. It is read in your browser, placed in the input, and converted only when you press Convert to JSON. The file is not uploaded or stored.
