Repair Excel
Frequently asked questions
Can you repair any corrupted Excel file?
Many of them — broken ZIP packages, malformed XML, and interrupted downloads recover well. Severely truncated files may be unrecoverable; the tool tells you honestly instead of producing a broken result.
Does it work with old .xls files?
Yes — legacy .xls files are read and rewritten as a clean modern .xlsx, which also repairs structural issues. Modern .xlsx and .xlsm are repaired in place.
Will I lose formulas or formatting?
Cell values and structure are preserved where readable. Some complex formatting, macros, or charts may be simplified when a file has to be rebuilt — recovering your data is the priority.
Is it free and private?
Yes — free, no watermark, no signup, and files are removed shortly after download.
Excel to CSV
Frequently asked questions
What happens to multiple sheets?
Each worksheet becomes its own CSV file, delivered together as a ZIP.
Does it keep formulas?
CSV stores values, not formulas — you get the computed cell values as plain text.
CSV to Excel
Frequently asked questions
Will it detect columns?
Yes — each comma-separated value goes into its own cell, row by row.
Is the result a real Excel file?
Yes — a standard .xlsx that opens in Excel, Google Sheets and LibreOffice.
