## **Questions**

<details>

<summary>

### Should I use ISERROR or IFERROR?

</summary>

To replace an error with another value, IFERROR is shorter, since =IFERROR(B2/C2,0) does what IF and ISERROR do in two steps. Use ISERROR when you only need TRUE or FALSE, for example in conditional formatting.

<summary>

### Does ISERROR catch

</summary>

Yes, it catches every error. ISNA catches only
