Common questions
Are my files uploaded to your servers?
No. CSV parsing runs entirely in your browser using native JavaScript. Your data is not sent to Filecraft servers.
Which plan is required?
CSV Viewer requires a Pro or higher plan.
What if my CSV doesn’t have a header row?
The first row is always treated as column headers. If your data has no header row, the first data row will appear as headers.
What delimiters are supported?
CSV Viewer supports comma-delimited files. Tab-separated or semicolon-delimited files are not supported in this version.
Does viewing change my data?
No. The viewer displays your data as a table but does not modify the original text. Copy and download actions return the original input exactly as entered.
Is there a size limit?
Pasted text is limited to approximately 5 million characters. For very large files, rendering may be slow depending on your browser. CSV Viewer is designed for inspecting data, not for spreadsheet-scale workloads.
