Creating a Digital Signature for Excel

Both the ESIGN Act and UETA ensure that electronic signatures are legally binding in the U.S., as long as the signer’s identity and intent are clearly established.
Details That Improve the Signature Experience
It’s not just about adding a signature — it’s about doing it well. These simple tweaks make a big difference:
- Use dark ink like black or navy for visibility on light backgrounds.
- Save your signature as a transparent PNG to avoid white box edges.
- Use high resolution to keep it sharp.
- Align the signature neatly with your approval text or notes.
- Lock the sheet after signing, if needed, to prevent changes.
Quick Checklist: Is Your Document Ready for a Signature?
Use this before you sign:
- All data is accurate and final.
- You’ve saved the file recently.
- You’re the final reviewer or approver.
- You want to limit changes after approval.
If all are true, it’s time to sign.

If you’ve already saved your signature as an image (recommended format: PNG), you can insert it easily:
- Go to the Insert tab.
- Click Pictures > This Device.
- Choose your signature image.
- Resize and drag it to the appropriate location on the sheet.
Tip: Use transparent backgrounds for a cleaner look.
