Frequently Asked Questions

A CSV is plain-text tabular data, not an Excel workbook. The recovery process finds a stored file, but you still need to check whether the recovered rows and separators make sense.

Locate the Last CSV Export

Search the folder where the application exported the CSV and check recent downloads or email attachments. A source application may be able to generate the same data again without disk recovery.

Check Recycle Bin, File History, and any cloud version. If you opened the CSV in Excel and saved it as .xlsx, look for that workbook separately.

Preserve the Data Source

Stop exporting new reports into the deleted CSV's original folder. Record the expected filename, date range, and approximate row count.

Connect a different physical disk for output. If the CSV contains sensitive records, avoid uploading it to an unfamiliar online recovery site.

Scan the Original Drive for CSV

Qiling Deep Data Recovery provides a visual scan of storage that Windows can detect. In this case, filter the source disk for the saved CSV rather than scanning a newly generated export. A listed file is only a candidate until you open and verify its recovered copy.

Step 1. Check Re-Export and Backups

See whether the originating application can safely re-export the same records. Inspect Recycle Bin and versioned backups before scanning.

Step 2. Choose a Deletion Scan

Use Fast Scan for a recent local deletion or Recycle Bin Scan if the bin was emptied. Choose USB/SD Scan if the export lived on removable media.

Step 3. Select the Export's Former Disk

Identify the original disk by letter and size, then scan it. Do not select the disk prepared to receive restored results.

Step 4. Compare CSV Candidates

Filter for .csv, compare file size and date, and preview text where supported. A matching name can still represent an older export.

Step 5. Save and Validate a Copy

Click Recover, save to another disk, and open a copy with the correct delimiter and encoding. Check header columns, sample rows, and the final row.

Avoid Misreading a Good CSV

Excel can display a valid CSV in the wrong columns when the delimiter or locale differs. Test the file with a text editor before concluding the recovery failed.

Compare totals or row counts with the source system. If the data can be re-exported accurately, keep that clean export as the primary copy.

Frequently Asked Questions

Is a CSV file the same as .xlsx?

No. CSV stores plain-text rows and does not preserve Excel formulas or workbook sheets.

Why are all values in one column?

The application may be using the wrong delimiter. Open the copy with the delimiter used by the export.

Can I recover rows that were never exported?

A disk scan cannot create records that were not written to the CSV. Re-export from the source application.
