FAQ
Frequently asked questions
Everything you need to know about excel to jsonl converter.
Which sheet is used?
The first sheet in the workbook is converted. Keep your data on a single sheet, since additional sheets are ignored.
Are empty cells included?
No. Empty cells are omitted from the JSON object entirely, which keeps the output compact and clean for log ingestion.
Is a header row required?
Yes. The first row is treated as the header, and every header cell must have a value or the tool reports an error.
Why convert Excel to JSONL?
JSONL is the natural format for pipelines, log ingestion, and streaming into data warehouses like BigQuery or Snowflake.
Are cell values exported as numbers?
No. Cells are read as they are formatted in the sheet and exported as strings, so for typed numeric data prefer a CSV or JSONL source.
