Frequently Asked Questions
What if my CSV uses a different delimiter (like tabs or semicolons)?
Currently the tool expects comma‑separated values. If your data uses a different delimiter, save the file as a comma‑separated CSV first. A delimiter selector may be added later.
Will the tool keep my cell values exactly as they appear?
Yes, the tool preserves the original text, including leading/trailing spaces and special characters.
Does it work with very large CSV files?
Up to about 50 MB of data should be handled smoothly in modern browsers. Larger files may slow down the tab; we recommend splitting the file with our CSV splitter first.
