How do you find errors and data quality problems in a CSV file?
Bad data in a CSV can break imports, skew calculations, and cause failures that are hard to trace back to their source. This tool scans your CSV for common structural and data quality problems: blank cells, rows with the wrong number of columns, and cells containing spreadsheet error values such as those that appear when a formula fails.
How to use it
Upload your CSV file and click Process file. The tool checks every row and every cell against the expected column count and flags anything that looks wrong. The output is a separate CSV listing each issue with its row number, column name, the type of issue, and the cell value. A count of total issues found appears as a summary. Download the issues file to review in a spreadsheet. Everything is processed in your browser and never uploaded to or stored by this site.
Tips
The tool flags blank cells as potential issues, but not all blank cells are errors depending on your data. Use the downloaded issues file to review each flagged item in context rather than treating every finding as a definitive problem. A high count of blank cells in one column often points to an optional field or a systematic data gap worth investigating. Spreadsheet error values like division-by-zero errors or broken references are flagged unconditionally, as they almost never belong in a data file.
Frequently asked questions
What specific error values does the tool detect?
The tool flags cells containing common spreadsheet error strings including REF, VALUE, DIV/0, N/A, and NAME errors. These patterns indicate formula errors that were pasted as values when the CSV was exported from a spreadsheet.
Does the tool fix the errors it finds?
No. The tool identifies and reports issues; it does not modify your data. Use the issues report to locate the problems in your source data and fix them before reprocessing.
