FAQ
Questions people ask about XLSX to CSV
What is lost converting XLSX to CSV?
CSV is plain tabular text, so formatting, formulas, charts, and multiple sheets are not carried over — cell values are kept, but a workbook collapses to a single sheet of data. Convert each sheet separately if you need more than one.
How are encoding and delimiters handled?
Output is standard comma-separated UTF-8, which imports cleanly into databases, data warehouses, and most SaaS tools.
Can I automate XLSX to CSV in a data pipeline?
Yes. The API is well suited to ingest pipelines — convert uploaded spreadsheets to CSV on the way into your database, ETL job, or reporting system.
Are my spreadsheets stored?
Uploaded files are deleted after processing. Default-destination output is purged after 7 days; use your own bucket to keep results.
