Spreadsheet safety

Make CSV files safer to open in Excel without destroying important values.

Join the waitlist for a CSV cleanup tool that detects values Excel may auto-convert, strip, round, or reformat before you send or edit operational files.

Example

Find CSV values Excel may break.

Preview how CSV columns can be checked before Excel silently changes IDs, SKUs, or ZIP codes.

Scientific notation risks

Detected findings

Tracking numbers may convert to scientific notation

high

Long numeric tracking values can become 1.23E+18 when opened in Excel.

ZIP codes with leading zeros detected

high

ZIP 02108 and 00544 would lose their leading zero if treated as numbers.

SKU-like IDs look numeric

medium

Several SKUs are all digits and should be protected as text.

Date auto-conversion risk

medium

Values like 03-04 may be converted into dates depending on locale.

FAQ

Questions before you join

Will this replace Excel?

No. The concept is to make CSVs safer to open, edit, and re-export when fields like SKUs, ZIPs, UPCs, or tracking numbers must stay as text.

What fields are risky?

Values with leading zeros, long numeric IDs, scientific-notation risks, date-looking strings, tracking numbers, postal codes, and SKU codes.

Would it modify my data?

The intended output is a safe cleaned file plus a report explaining which fields were protected and why.

What should I put in the use case box?

Mention the fields Excel keeps breaking for you, such as ZIP codes, tracking numbers, UPCs, customer IDs, or SKU codes.
